He and his wife had worked to fill out the necessary paperwork but never heard back. He contacted my office and we were able to intervene and ensure he got his health coverage granted. If you’re a #CA04 resident facing an issue navigating a federal agency, please call my nearest office.

In just a few years, my renewable energy investments in the Inflation Reduction Act provided over $208 million in investments right here in #CA04. I’ll keep working to help restore them. www.pressdemocrat.com/article/opin...

Close to Home: House GOP gutted my renewable energy investments

These investments were fully paid for and created jobs, reduced climate impacts and boosted our global standing.

I’ll continue to work alongside organizations like the California Medical Association to fight cuts to health care access. Everyone deserves to have high-quality, affordable care.

Letter from the California Medical Association dated August 12, 2025, titled A CMA THANK YOU and addressed to California Democratic Members of Congress. CMA thanks them for leadership in stopping catastrophic cuts to Medicaid and the ACA in HR 1, which would have cost California $226 billion, caused nearly 4.5 million to lose coverage, and closed hospitals and clinics. The letter warns cuts would worsen physician shortages, mental health and OB deserts, and eliminate over 200,000 health care jobs, calling the impact “unspeakably cruel.” CMA stresses Medicaid and the ACA are vital for families’ health and economic security. Despite threats, CMA pledges to keep fighting and is grateful Congress stood with them. CMA commits to working with Congress to restore coverage, improve access to physicians, address shortages, and ensure care for all. Signed by Shannon Udovic-Constant, MD, President.

Thompson leads group seeking support for universal background checks

Following the mass shooting in a Midtown Manhattan office building in late July, Gun Violence Prevention Task Force Chairman Mike Thompson (CA-04), Democratic Leader Hakeem Jeffries (NY-08), and Representative Jerrold Nadler (NY-12) led the New York Democratic delegation in a letter on Friday calling on every Republican representing New York in Congress to back universal background checks.

Proud to co-lead the bipartisan U.S. Bicycle Production and Assembly Act to give bike manufacturers the foothold they need to grow a thriving industry right here in the United States.

Rep. Mike Thompson@mikethompson.house.govAug 19(source)

Ninety-seven percent of bicycles purchased in the United States are made elsewhere. It’s time we change that. spectrumlocalnews.com/mo/st-louis/...

U.S. bicycle industry shifts to adapt to tariffs on top bike exporters

With most bicycles made in Asia, imports were down 11% through the first six months of the year

I’ll keep working to help protect our trade relationships, ease the cost of living, and enforce Congress’ constitutional authority over tariff policy.

Rep. Mike Thompson@mikethompson.house.govAug 18(source)

The cost of living is already too high for hardworking Americans. Now, the President’s trade war is raising prices even further. www.npr.org/2025/08/12/n...

Inflation remains elevated as Trump's tariffs take hold

Inflation remained elevated last month as President Trump's tariffs continued to make their way into the prices that consumers pay. The average cost of living in July was up 2.7%.

I’ll keep working to restore these investments that the President and Congressional Republicans gutted in their One Big Ugly Bill.

Rep. Mike Thompson@mikethompson.house.govAug 16(source)

Three years ago, President Biden signed our Inflation Reduction Act into law, which included the renewable energy investments I wrote. Since then, an estimated $208 million has already been invested in renewable energy projects in our district alone. rhg.com/research/ass...

She’s right, our national debt is out of control and will saddle our kids and grandkids. Yet Rep. Mace and nearly every House Republican voted to pass their One Big Ugly Bill, which non-partisan experts agree will add another $4.5 trillion to our debt. Read more for yourself.

Rep. Mike Thompson@mikethompson.house.govAug 15(source)

#FactCheckFriday My Republican colleague Rep. Nancy Mace expressed concern over our national debt this week, stating that this is “a bill our kids can’t afford to pay.”
