No hardworking family should ever have to make that choice.

Rep. Mike Thompson@mikethompson.house.govNov 2(source)

Middle-class families across California are being priced out of the care they need. One family in our district is now facing an $800 monthly increase in their health insurance premium — forcing them to choose between paying bills and keeping their family covered.

This isn’t political. It’s personal.

Rep. Mike Thompson@mikethompson.house.govNov 1(source)

Families across our district are feeling the devastating impact of the federal shutdown and the lapse in healthcare tax credits. For small business owners in Sonoma County, that means premiums doubling overnight — and losing access to the doctors and medicines they rely on.

We don’t need to go back to the days of mutually assured destruction. Resuming nuclear weapons testing doesn’t make America safer. It makes the world more dangerous. www.bbc.com/news/article...

Trump says nuclear weapons testing to resume in US after more than 30 years

It is necessary for the US to keep pace with weapons programmes in China and Russia, the president says.

These investments were fully paid for, they lowered costs, they created jobs, and they positioned America to lead in the global clean energy economy. That’s why I’m leading the fight now to restore these critical climate provisions.

Rep. Mike Thompson@mikethompson.house.govOct 31(source)

I haven’t met anyone in our community who said, ‘I wish Congress would raise my energy bills. But that’s exactly what happened when Congressional Republicans gutted the clean energy tax incentives I had signed into law.

Aidan was an intern in my D.C. office. I spoke with him about why he wants to get involved in politics and what he's hoping to get out of this experience through the University of California's Washington D.C. Program.

Betsy Marchand shattered glass ceilings in Yolo County and dedicated her life to public service long after her time on the Board of Supervisors. Her leadership and vision helped shape Yolo County and California for the better.

Betsy Marchand, first female Yolo County Supervisor, dies at 89

Trick-or-treaters aren’t the only ones getting spooked — candy prices have climbed nearly 11 percent since last year! Tootsie Roll Lollipops alone are up 34 percent, thanks to the President's tariffs and rising costs. Even Halloween isn’t safe from his scary economic policies.
