Messmer Introduces Bill to Advance Ready Reserve Force Modernization
Position: Rep. Messmer introduced a bill directing the Navy and Maritime Administration to prioritize finalizing design requirements for new Ready Reserve Force sealift vessels and to brief Congress on plans and funding to build them. The release states that replacing the aging fleet is necessary for military readiness.
WASHINGTON, D.C. – Rep. Mark Messmer (R-IN), a member of the House Armed Services Committee, today introduced the Ready Reserve Force Modernization Accountability Act. The bill directs the Navy and Maritime Administration to prioritize finalizing design requirements for new sealift vessels and brief Congress on plans to build and fund them.
The Ready Reserve Force (RRF) is a fleet of approximately around 50 vessels that can carry troops, equipment, fuel, and supplies across oceans during a crisis. It provides nearly half of the federal government’s surge sealift capacity. Its ships are more than 45 years old on average.
“Our adversaries should think twice before challenging the United States because they know we can bring a logistical force to a fight that is unmatched anywhere in the world,” said Rep. Mark Messmer. “The Ready Reserve Force is a major part of that advantage. We need to replace its aging ships so our military can continue to move troops, equipment, and supplies wherever they are needed. This bill is a step toward maintaining that edge.”
“The Ready Reserve Force (RRF) is only as ready as its ships, and too many of them were built decades ago,” said Senator Dave McCormick. “We need to treat this moment with the urgency it deserves by finalizing the design for new RRF vessels and laying out how they will be built and paid for. Shipyards can't hire, train, and invest based on intentions alone. I applaud Representatives Messmer and Courtney for recognizing the stakes and introducing this bipartisan companion to S. 4630.”
“There’s no question that maintaining our nation’s Ready Reserve Force is national security priority, and the Seapower and Projection Forces Subcommittee remains committed to enabling the Navy, TRANSCOM, and MARAD to recapitalize the fleet. That’s why, in the FY23 NDAA, we mandated the use of the successful vessel construction manager model for this program. I look forward to the continued work between Congress and the Navy to ensure successful deliveries of new RFF vessels,” said Rep. Joe Courtney.
The Ready Reserve Force Modernization Accountability Act directs the Secretary of the Navy and the Maritime Administrator to prioritize finalizing design requirements for new RRF vessels.
The bill also requires the Navy, in coordination with the Maritime Administration, to brief Congress within 180 days. The briefing must cover the status of the new vessel design, plans for a vessel construction manager program, funding for the authorized 10-ship construction program, and how purchases of new and used vessels will work together during the transition.
The legislation aims to support military readiness and give domestic shipbuilders greater clarity about the path to replacing the fleet.

Messmer Hosts Tax Event Highlighting the Benefits of the One Big Beautiful Bill
Position: The release supports the One Big Beautiful Bill, asserting it provides tax relief by preventing a tax increase, making Tax Cuts and Jobs Act provisions permanent, and expanding deductions for overtime pay and seniors. It also calls for future tax cuts and job-creating policies.
TERRE HAUTE, IN – Today, Rep. Mark Messmer (R-IN) hosted a Tax Event alongside Rep. Rudy Yakym (R-IN) to discuss how the One Big Beautiful Bill (OBBB) is delivering lasting tax relief for Hoosier families, workers, seniors, and small businesses. The event brought together local financial professionals, CPAs, bankers, and business leaders to examine the law's impact on Indiana's economy.
“The One Big Beautiful Bill prevented the largest tax increase in history from crushing hard-working Americans, while making many pro-growth tax policies permanent for all families and businesses,” said Rep. Messmer. “Today’s discussion provided an opportunity to speak directly with Hoosiers in our community and discuss new ways we can deliver relief with future tax cuts and job creating policies.”
During the forum, participants highlighted the positive impacts of the law’s permanent extension of provisions in the Tax Cuts and Jobs Act and celebrated the bevy of expanded deductions which are creating new financial opportunities for American families and small businesses. Stakeholders also discussed the benefits of new deductions for overtime pay, and enhanced deductions for many senior citizens, which effectively eliminate federal taxes on Social Security checks, ensuring Hoosiers, many on a fixed income, keep more of their money. Altogether, the impact of the OBBB is promoting economic stability and growth across Indiana.

Messmer Highlights Indiana’s Workforce Development Leadership at Apprenticeship Roundtable
Position: Rep. Messmer states that Indiana's apprenticeship model provides a proven template for federal workforce development policy and that expanding apprenticeships can help close the skills gap.
EVANSVILLE, IN – Today, Rep. Mark Messmer (R-IN) hosted an Apprenticeship Roundtable at Ivy Tech Community College in Evansville to discuss how Indiana’s nationally recognized apprenticeship model can help strengthen workforce development nationwide. The event convened federal, state, education, and industry leaders to examine policies that expand career pathways and address America's workforce needs.
“Indiana has demonstrated that strong partnerships between employers, educators, and government can prepare workers for rewarding careers while meeting the needs of our economy,” said Rep. Messmer. “As Congress explores ways to strengthen workforce development, our state provides a proven model for expanding apprenticeships, closing the skills gap, and creating opportunities for hardworking Hoosiers.”
Participants discussed Indiana’s leadership in registered apprenticeships, the role of community colleges in preparing the next generation of skilled workers, and opportunities to build on successful state programs through federal workforce policy. The conversation also highlighted the importance of collaboration between employers, educators, and government to meet growing workforce demands in key industries.

Position: Rep. Messmer states he will continue working to strengthen the VA, improve access to care, and pursue benefit expansion and legislative priorities for veterans in Indiana's Eighth District.
VINCENNES, IN – Today, Rep. Mark Messmer (R-IN) convened a Hoosier Veterans Roundtable at Vincennes University, bringing together local, state, and federal veterans organizations to discuss services and care for Hoosier veterans. The discussion focused upon benefit expansion, strengthening coordination among organizations, and identifying legislative priorities to best serve those who make our nation so proud.
“Our veterans fulfilled their commitment to America, and we will always fulfill ours to them,” said Rep. Messmer. “I appreciate everyone who joined today’s discussion, and I will continue working to strengthen the VA, improve access to care, and fight for the veterans of Indiana's Eighth District.”
Representatives from the U.S. Department of Veterans Affairs, the House Committee on Veterans Affairs, the Indiana Department of Veterans Affairs, and local Veteran Service Organizations shared updates on ongoing initiatives and discussed the needs of veterans across Southern Indiana, including access to care in rural communities.

Messmer Celebrates Passage of the FY27 National Defense Authorization Act in the House of Representatives
Position: The release applauds House passage of the FY2027 National Defense Authorization Act and urges the Senate to act swiftly to send it to the President. It describes the bill as strengthening military readiness, national security, and the defense industrial base.
WASHINGTON, D.C. – Today, Rep. Mark Messmer (R-IN), a member of the House Armed Services Committee and co-chair of the Congressional Hypersonics Caucus, applauded passage of the Fiscal Year 2027 National Defense Authorization Act (NDAA) in the House of Representatives.
“My Republican colleagues and I are proud of our collaboration with President Trump to advance a national defense agenda that puts America first, and I am pleased the House has passed the Fiscal Year 2027 National Defense Authorization Act,” said Rep. Messmer. “The passage of this historic investment in our nation’s warfighters strengthens our military, bolsters our national security, and helps ensure the United States maintains the strongest, most capable, and most lethal fighting force in the world. I urge our colleagues in the U.S. Senate to act swiftly and send this legislation to the President’s desk.”
The FY27 National Defense Authorization Act includes provisions to revitalize the defense industrial base, restore critical weapons stockpiles, raise servicemember pay, strengthen missile and nuclear deterrence, accelerate the deployment of emerging technologies like hypersonics and autonomous systems, and improve accountability within the Department of War.
The legislation also expands domestic manufacturing capacity, strengthens supply chain security, supports workforce development initiatives, and reduces barriers for small businesses and innovative defense contractors.
The NDAA also contains several wins for Indiana’s 8th Congressional District, including:

House Education and Workforce Committee Passes Messmer Deregulation Legislation
Position: Rep. Messmer opposes federal heat safety standards for workplaces, arguing they impose unnecessary regulatory burdens on businesses. The release advocates for repealing OSHA's proposed heat injury and illness prevention rule.
WASHINGTON, D.C. – Today, the House Education and Workforce Committee advanced Rep. Mark Messmer's (R-IN) Heat Workforce Standards Act of 2025 (H.R. 6213) during a committee markup. The legislation repeals the Biden-Harris Administration's proposed federal heat standards, which impose burdensome, one-size-fits-all mandates, and unneeded and excessive penalties on American businesses and institutions.
“As a small business owner, I know firsthand that ineffectual government regulation makes it harder for employers to grow their business, create job opportunities, and invest in their workforce,” said Rep. Messmer. “The House Education and Workforce Committee's approval of my Heat Workforce Standards Act is an important step toward rolling back more of the unnecessary Biden-era regulations that hamper America’s development and expansion. I look forward to advancing this bill through the full House to continue reducing trivial red tape which is depressing the success of our great nation.”
The Biden Administration’s Occupational Safety and Health Administration (OSHA) attempted at the last minute to fast-track a policy known as “The Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings.” In practice, the rule would have forced nearly every American business and institution to follow rigid, one-size-fits-all, federal workplace standards based on predetermined temperature thresholds, regardless of industry, climate, or existing safety protocols.
This terrible rule would create a one-size fits all regulatory approach for most of the American workforce that experience exposure to temperatures of 80 degrees Fahrenheit for more than 15 minutes in any given hour. State governments already have the authority to establish occupational safety and health standards and are required to have their plans be “at least as effective” as Federal OSHA standards.
If it had been implemented, the Biden’s Heat Rule would:

Messmer Applauds Passage of the Sunshine Protection Act in the House of Representatives
Position: Rep. Messmer voted in support of H.R. 139, the Sunshine Protection Act of 2025, which would make Daylight Saving Time permanent nationwide and end the biannual clock changes.
WASHINGTON, D.C. – Rep. Mark Messmer (R-IN) voted in support of H.R. 139, the Sunshine Protection Act of 2025, in the House of Representatives, to make Daylight Saving Time permanent and end the twice-yearly practice Americans endure of changing the clocks backwards and forwards.
“Hoosiers are tired of this needless activity,” said Rep. Messmer. “Making Daylight Saving Time permanent is long overdue and a needed relief from an outdated practice that no longer serves the needs of our modern economy. I have heard from the citizens of Indiana’s 8th District, and I am proud to support the Sunshine Protection Act.”
The Sunshine Protection Act would establish permanent Daylight Saving Time nationwide, eliminating the need to “spring forward” and “fall back” each year. By ending the biannual time change, the legislation aims to provide greater consistency for families, businesses, schools, and commuters while reducing the disruptions associated with changing the clocks. This bill has the support of the American Farm Bureau.

Messmer Condemns Chemical Abortion Crisis at Republican Study Committee Roundtable
Position: Rep. Messmer supports federal legislation to establish penalties for non-consensual administration of abortion-inducing drugs and to strengthen protections against forced abortion.
WASHINGTON, D.C. – Today, Rep. Mark Messmer (R-IN) participated in a Republican Study Committee (RSC) roundtable hosted by Rep. Sheri Biggs (R-SC) focused on the growing chemical abortion crisis, the impact of abortion-inducing drugs, and legislative efforts to strengthen protections for women and improve accountability.
“No woman should ever be subjected to a forced abortion, and those who commit these acts should face the full force of the law,” said Rep. Messmer. “As chemical abortion drugs become more widely available, Congress has a responsibility to ensure strong protections are in place to safeguard women and hold bad actors accountable. I am proud to support legislation that addresses these serious crimes and helps prevent future tragedies.”
During the discussion, Rep. Messmer highlighted his Forced Abortion Prevention and Accountability Act, legislation he introduced to establish federal penalties for the non-consensual administration of abortion-inducing drugs and hold accountable those who facilitate these acts.

Messmer and Walberg Host Field Hearing on the Future of Mining in Southwest Indiana
Position: Representatives Messmer and Walberg hosted a field hearing to examine workforce development, mine safety, and domestic energy production in the mining industry, emphasizing the importance of maintaining a strong domestic mining sector for energy independence and economic security while highlighting concerns about federal regulations.
WASHINGTON, D.C. – Rep. Mark Messmer (R-IN) joined the chairman of the House Education and Workforce Committee, Rep. Tim Walberg (R-MI), for a field hearing in Fort Branch, Indiana, titled “Protecting Workers and Powering America: The Future of Mining.”
The hearing examined workforce development, mine safety, domestic energy production, and the future of the mining industry in Indiana and across the United States. The hearing was held at the Vincennes University Gibson County Center for Advanced Manufacturing and Logistics.
“I am very impressed with the facilities and education programs at Vincennes University, which are improving the entire mining worker-safety component,” said Rep. Messmer. “VU is training future generations of leaders so that they meet the demands of an ever-evolving industry. I am so proud that Hoosier mining is powering our state grids, and that it is an essential contributor to the energy and economic security of our entire country.”
“Collaboration between government and the private sector leads to safer workplaces, an educated workforce, and a stronger mining industry,” said Education and Workforce Committee Chairman Tim Walberg (R-MI). “I was grateful for the productive conversations with our witnesses about ways to unleash the mining industry’s potential in a way that protects miners and benefits the communities in which they live and work. America’s miners power our nation, and their wellbeing must always come first.”
“Vincennes University appreciates Congressman Messmer and Chairman Walberg for highlighting the importance of mining safety, workforce development, and the future of American energy production,” said David Tucker, Vice President of Workforce Development and Community Services at Vincennes University. “As Indiana’s designated recipient of Mine Safety and Health Administration grant funding for miner training and retraining, VU remains committed to preparing the next generation of mining professionals through hands-on, industry-driven training that supports safe and reliable mining operations across the region.”
During the hearing, witnesses highlighted the importance of maintaining a strong domestic mining industry to support America’s energy independence, manufacturing sector, and electric grid reliability. Testimony also focused on the role Indiana coal continues to play in delivering affordable and reliable energy for families and businesses.
Witnesses discussed how modern mining operations have evolved through advanced technology, stronger safety standards, autonomous equipment, and enhanced dust monitoring systems. Industry leaders also addressed workforce shortages and the need to combat outdated misconceptions surrounding careers in mining.
Additionally, witnesses raised concerns regarding the Biden-Harris Administration’s 2024 silica rule, arguing the regulation imposes costly burdens on operators without improving worker safety and could place additional strain on mining communities and jobs. Testimony also examined how previous enforcement practices under the Mine Safety and Health Administration (MSHA) created unnecessary compliance challenges for mine operators.
Both Messmer and Walberg emphasized the importance of supporting workforce training programs, promoting safe mining practices, and creating a regulatory environment that allows the mining industry to continue growing and supporting American energy production.

ICYMI: Indiana Rep. Mark Messmer in the Washington Examiner: “Southern Indiana Mining is Powering American Prosperity”
Position: Rep. Messmer advocates for continued coal mining in southern Indiana as essential to American energy independence and economic prosperity, and criticizes the Biden-Harris administration's 2024 silica dust rule as poorly implemented despite acknowledging the legitimate safety concern it was meant to address.
WASHINGTON, D.C. – Indiana Rep. Mark Messmer (R-IN) was recently featured in the Washington Examiner with an op-ed highlighting the importance of southern Indiana’s mining industry, mine safety, workforce development, and American energy independence.
In the piece, Rep. Messmer discusses Indiana’s role as one of the nation’s leading coal-producing states and the vital contributions Hoosier miners make to powering the American economy and supporting the nation’s industrial base.
Rep. Messmer additionally highlighted the importance of workforce development and modern mining education programs at schools like the Vincennes University Gibson County Center for Advanced Manufacturing and Logistics, the location of the House Education and Workforce Committee’s field hearing in Fort Branch, Indiana.

Southern Indiana mining is powering American prosperity
In Indiana, we are familiar with the important impact of the mining industry. We rank among the top 10 coal-producing states, and the industry contributes over $750 million annually to the Hoosier economy. We are proud that our miners play a pivotal role in our economy, as well as in America’s national security, by helping power the United States industrial base each and every day.
The stark reality is that the mining industry is not just a crucial source of energy, but also an important job producer in this country, powered by the strength and hard work of American laborers.
The mining industry powers our country’s energy grid, contributes to critical infrastructure needs, and secures the raw materials that keep our economy thriving and competitive. But the real measure of its success is not how much product is produced, but rather the health and safety of the miners who put their lives on the line each day. This requires workplace protections and safety standards to be observed with the utmost intensity.
The Mine Safety and Health Administration, or MSHA, helps ensure the rules and regulations protecting miners are properly followed. Through regular inspections, updated safety standards, and consistent enforcement, MSHA works to ensure no corners are cut and no precautions are ignored.
However, the best ideas and solutions should not come from someone sitting behind a desk in Washington, D.C., but rather from those in the field who have firsthand experience with what can go wrong, why it happens, and how injuries can be prevented. MSHA collaborates with miners, operators, engineers, and industry leaders who all bring important perspectives to the table.
Unfortunately, that kind of balance and teamwork was missing from some recent agency decisions. The Biden-Harris administration’s 2024 silica rule was intended to address a real concern shared by everyone involved, protecting miners from harmful dust exposure. But the way this rule was written and implemented failed to achieve its intended goals.
Instead of embracing practical solutions like job rotation or flexible compliance strategies, the rule imposed rigid, one-size-fits-all requirements that have created unnecessary burdens for miners and operators alike. In fact, it resulted in costly overreach and unnecessary redundancy.
We should not have to choose between protecting workers and preserving livelihoods. We can do both, but only by creating policies grounded in reality, not radical ideology.
The House Education and Workforce Committee is holding a field hearing right here in southern Indiana at the Vincennes University Gibson County Center for Advanced Manufacturing and Logistics, a school that trains the next generation of miners.
At the hearing, we will present the facts about mining and allow experts to answer questions and explain the work being done to protect workers and strengthen the industry. Members of Congress participating in the event will also have the opportunity to step into a mine simulator on campus and tour the Peabody Mine in Francisco, Indiana.
Today’s miners are highly trained operators of advanced technological systems and intricate equipment. Virtual reality training tools, simulation-based learning, and continuous reskilling are essential to keeping workers safe and providing hands-on experience in a secure environment while they learn their trade.
America’s miners deserve nothing less than our full commitment to their safety. That means strong and effective oversight from MSHA, smart policies that balance innovation with practicality, and a continued focus on training and workforce development.
With this practical approach, we can ensure we are doing everything possible to educate the next generation of mining engineers, protect good-paying jobs, and grow an industry that remains vital to the prosperity of the United States of America.
