When I chaired the Tax Subcommittee, we strengthened enforcement by funding the IRS to audit these firms and hold them accountable.

Rep. Mike Thompson@mikethompson.house.govJan 9(source)

The U.S. Treasury found that wealthy venture capital, private equity, and real estate investment firms are exploiting tax loopholes costing taxpayers more than $100 billion.

Push to Audit Private Equity and Venture Capital Falters Under Trump

Specialists have left the I.R.S. and audits have been abandoned since the president returned to office.

Rep. Mike Thompson@mikethompson.house.govJan 9(source)

The CDC’s decision to scale back childhood vaccine recommendations puts lives at risk. I joined 115 Democrats to fight for healthy children and oppose guidance that puts our kids in danger.

Rep. Mike Thompson@mikethompson.house.govJan 9(source)

Team Thompson is always ready to help you navigate issues with the federal government. Hear from Anthony in Lake County about how we were able to help!

Rep. Mike Thompson@mikethompson.house.govJan 8(source)

I voted YES to extend the ACA premium tax credits. Read my full statement.

Rep. Mike Thompson@mikethompson.house.govJan 8(source)

Democrats fought to get the extension of the ACA tax credits to the floor for a vote. Now, let’s get it passed so we can bring down costs and ensure Americans can keep their coverage.

Rep. Mike Thompson@mikethompson.house.govJan 8(source)

His memory lives on through the room named in his honor in the Capitol, a lasting tribute to a life and career cut far too short. We must continue the fight to end gun violence and ensure tragedies like this never happen again.

Rep. Mike Thompson@mikethompson.house.govJan 8(source)

We lost Gabe Zimmerman in the same shooting 15 years ago that killed five others and injured 14, including former Congresswoman Gabby Giffords. Gabe was the first congressional staffer killed in the line of duty. It was a devastating loss to his family, his colleagues, and the institution we serve.

Rep. Mike Thompson@mikethompson.house.govJan 8(source)

Secretary Noem needs to resign, and ICE needs to get out of Minnesota.

Rep. Mike Thompson@mikethompson.house.govJan 8(source)

15 years after the Tucson shooting, we remember the six lives lost, stand with the survivors, and recommit to preventing gun violence. Gabby Giffords has shown what courage and action can achieve, and our work is far from done.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

Deeply concerned by ICE's killing of a woman in Minneapolis. These indiscriminate raids are scaring and hurting people across our country. Secretary Noem must immediately cease ICE operations in Minneapolis and investigate the shooting immediately. Enough is enough. apnews.com/live/minneap...

Live updates: ICE officer shoots and kills a woman during the Minneapolis immigration crackdown

After a federal officer shot and killed a Minneapolis motorist, Minneapolis Mayor Jacob Frey rejected Homeland Security's claim that the ICE officer acted in self-defense.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

It’s day 7 of 2026 and there have been 8 mass shootings this year. That’s already more mass shootings than days in the year so far. That’s unacceptable. We need to keep guns out of the hands of those who are a danger to themselves or others.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

Stood with Democratic veterans to oppose an unnecessary war in Venezuela. As a combat veteran, I opposed the war in Iraq, and I will oppose any military intervention in Venezuela. We will not send our military members to fight for oil.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

I’ll continue fighting to protect our coastline and pursue energy policies that actually work for families.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

This administration’s offshore drilling proposal puts our marine ecosystems and coastal economies at risk while offering little benefit to lower energy costs. I wrote oil spill response and cleanup laws when I was in the State Senate, and I know how devastating a spill would be for the North Coast.

Thank you, JT, for the work you’ve done to prepare for the Black History Month Celebration this year and for the last nine years of making a positive impact in our community.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

James Thompson, founder of the Napa Black History Month Celebration at CrossWalk Church, has long been a strong voice for the black community in Napa.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

Had the chance to tour Puertas Abiertas’ new building and learn more about the vital support they provide to Napa County’s Latino community. From health care to social services, they show up every day to serve our neighbors.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

She continues to make history as the first Latina elected to the Board—and now as its first Latina Chair. I look forward to continuing to work with her to strengthen Sonoma County and address the impacts of federal funding cuts.

Rep. Mike Thompson@mikethompson.house.govJan 7(source)

Congratulations to Rebecca Hermosillo on being selected Chair of the Sonoma County Board of Supervisors! I’m incredibly proud of Rebecca. When she worked with me, she was a tireless advocate for Sonoma County and an outstanding leader in my Santa Rosa district office.

Supervisor Rebecca Hermosillo to lead Sonoma County Board of Supervisors through challenging year as chair

The Sonoma County Board of Supervisors unanimously selected Supervisor Rebecca Hermosillo to serve as chair in 2026. She is the first Latina to serve in the role in Sonoma County.
