As an outdoorsman and conservationist, I know how important our national wildlife refuges are to our communities and environment. That’s why I’m proud to lead a bipartisan resolution recognizing National Wildlife Refuge Week.
I’m fact-checking myself today. I said President Trump was giving Argentina $20 billion. Now it’s $40 billion. Think of what that kind of money could do for Americans. But instead the President is raising that money for his authoritarian friend. #FactCheckFriday apnews.com/article/trum...
CLOSED: 28 days and counting. I agree with my Republican colleague Rep. Kevin Kiley — Speaker Johnson needs to bring Congress back to work. We have urgent business left undone: lowering the cost of healthcare, pass the Farm Bill, restore Medicare telehealth access for seniors, and so much more.
If ACA tax credits expire, millions of Americans of all ages will lose their coverage, and hospitals across our country will struggle to stay afloat. Speaker Johnson must bring Congressional Republicans back to work with Democrats to extend these life-saving credits.
Democrats stand united — we won’t let Speaker Johnson and Congressional Republicans trample on Americans’ healthcare. We’re here, ready to work, because that’s what the people sent us here to do. It’s time for Speaker Johnson to bring Republicans back to Washington.
The answer is clear: Reopen the government, save hospitals, stop healthcare premium price hikes. If Speaker Johnson doesn’t bring Congressional Republicans back, our healthcare system nationwide will crumble under soaring costs and strain — and every American will feel the impact.
While hardworking public servants are being forced to go without pay, members of Congress should not be collecting a paycheck. I’m refusing my salary during the shutdown, and urging all members of Congress to come back to Washington to reopen the government.
We’re in week three of the federal government shutdown — and still, Speaker Johnson refuses to call the House back to work. Republican leadership neglects governing while families are opening letters from their insurers showing skyrocketing premium hikes. Democrats are fighting for your healthcare.
Take it from Doctor and Representative @repdexteror.bsky.social - Republican cuts to healthcare will impact ALL Americans. Democrats are here fighting to reopen the government and protect your healthcare. Congressional Republicans are still on vacation for the third week in a row.
The Trump administration’s decision to eliminate funding for Sonoma State’s teacher program hurts our kids. This program gave future teachers the support they needed to succeed. At a time when our schools face teacher shortages, cutting investments in education is the last thing we should be doing.
Rural communities like Clearlake rely on strong federal investment in health care. Adventist Health’s withdrawal from this critical clinic project is a direct result of reckless cuts to Medicaid under the Big Ugly Law. Read my full statement.
Every day the shutdown continues, millions of Americans are pushed closer to losing their health care. I joined over 150 of my Democratic colleagues in urging Speaker Johnson to bring the House back into session and join Democrats in protecting affordable coverage by extending the ACA’s tax credits.
Vacaville residents: My team is hosting in-person office hours today, October 14th from 2 to 4pm. Please drop in to discuss with my team any support you may need and stay tuned for more sessions throughout our district.

Today we celebrate 250 years of the United States Navy — a proud legacy of service, courage, and commitment to defending our nation. As an Army veteran, I’ll admit there’s always been a friendly rivalry with the Navy — but one thing’s certain: no one serves with more dedication.
Proud to join Napa Day Against Hate and community leaders across Napa County to reaffirm a simple truth: our diversity makes us stronger. Whether it’s supporting our LGBTQ+ neighbors or standing up to intolerance wherever it appears, I’ll always fight for a community where everyone belongs.
