I was proud to support the federal grant program that helped make this project possible, and I’ll keep fighting to expand access to safe, affordable housing for families across our district. Thank you to all who made this project possible. Fortunate to be part of a remarkably generous community.

Rep. Mike Thompson@mikethompson.house.govMar 13(source)

Great to join our St. Helena community to cut the ribbon on the new Pope Street Workforce Housing Project. This development will bring new affordable rental homes to our community and help ensure local workers can live where they work.

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

Had a great conversation with students at Davis High School about my path to public service, what it’s like working in Congress, and how young people can get involved in our democracy. Their questions and ideas give me a lot of hope for the future.

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

Groceries are already too expensive, and now fertilizer supply disruptions could push food prices even higher. Farmers are paying the price, and soon families at the checkout line will too. We need to end this administration's war in Iran and focus on delivering real relief for the American people.

Food prices could rise as Iran conflict disrupts fertilizer supply chain

The Iran conflict is disrupting fertilizer shipments through the Strait of Hormuz, raising supply concerns and potentially increasing global food inflation.

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

Hosted an agriculture roundtable with Senator Chris Cabaldon to hear directly about the challenges facing our ag families. Our ag community feeds the world, and I’ll keep working with our state and federal partners to make sure they have the support they need.

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

I voted against creating ICE because I believed it lacked the guardrails necessary to prevent abuse of power, and sadly, those concerns have proven justified. ICE has become a rogue agency. We must hold leaders like Kristi Noem accountable and stop ICE from terrorizing communities across our country

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

Gas prices are rising because this president’s war in Iran has disrupted shipping through the Strait of Hormuz — a vital waterway that carries about 20% of the world’s oil. We’re already spending over $1 billion a day on this illegal war, and now Americans are paying even more at the pump.

Rep. Mike Thompson@mikethompson.house.govMar 12(source)

The only problem I have with Kristi Noem being fired as head of DHS is that she didn’t take Stephen Miller and the rest of this president’s thugs with her. ICE has become a rogue agency, and I'm fighting to hold them accountable and stop them from terrorizing our communities.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

Thanks to the North Bay Leadership Council for hosting our conversation in Santa Rosa. We discussed the challenges coming out of Washington and the work we’re doing to strengthen our economy, invest in clean energy, tackle housing costs, and support North Bay communities.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

I will never stop fighting for single-payer solutions like Medicare for All so every American can get the care they need.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

In the next Congress, I will serve as Chair of the Health Subcommittee on the Ways and Means Committee, where I’ll help lead Democrats’ efforts to ensure every American has access to health care.

Rep. Mike Thompson@mikethompson.house.govMar 11(source)

The talent, drive, and thoughtfulness of the students in our district never ceases to impress me. My Student Leadership Council has given the tools to success to more than 360 future leaders and counting.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

The Vine Trail is a treasure for our community, and I’m glad I could help secure the funding to keep this project moving forward.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

This investment will expand safe, accessible transportation options for walkers, cyclists, and families — and it’s always great to see young families out on the trail pushing strollers or teaching their kids how to ride bikes.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

Proud to have secured $850,000 for the Napa Valley Vine Trail to help connect Yountville and St. Helena.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

The American people need real relief, and I’m fighting to bring down costs.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

Affordability isn’t a hoax. It’s a real challenge families in our community face every day. That’s why I introduced the American Affordability Act, a plan to lower costs for everything from education and health care to energy, child care, and more.

Rep. Thompson's Napa roundtable looks at affordability issues

Rep. Mike Thompson convened a roundtable of local leaders to discuss high prices and what to do about them.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

War should never be started without a plan, without Congress, and without the American people. We’ve already lost seven American servicemembers and spent billions of dollars. As a combat veteran, I’m standing up to say: no more forever wars.

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

It’s inspiring to see so many young people already engaged and thinking about their civic responsibilities!

Rep. Mike Thompson@mikethompson.house.govMar 10(source)

Had a great time speaking with 8th grade students at Robert Louis Stevenson Middle School in St. Helena. We talked about the Constitution, how Congress works, and the role each of us plays in our democracy.
