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.
Today, we honor Indigenous Peoples’ Day — a time to celebrate the cultures, contributions, and resilience of Native communities. We recognize the profound impact Indigenous peoples have had in shaping our nation today and every day.
If your neighbor’s house catches fire, your home could be in danger too—health care works the same way. When people lose coverage because ACA tax credits expire, everyone’s health is at risk. Democrats are fighting to make sure families can keep their care and stay protected.
Republican Leadership has told its members not to host town halls, so I'm glad to welcome their constituents to join mine! 42 U.S. Code 18081(a)(1) prohibits undocumented immigrants from buying healthcare on the ACA healthcare exchange. Hope this helps.
Families are already getting notices that their premiums are going up—some doubling overnight due to Congressional Republicans' inaction. No one can afford that. We’re fighting to protect your health care and stop these crushing cost increases.
Visited Aliados Health in Petaluma, where I met with local leaders and Covered California enrollment counselors who help thousands of Sonoma County families get access to affordable, quality health care.
Americans of every party stripe will suffer if Congressional Republicans don’t work with Democrats to prevent rising health care premiums and protect affordable healthcare. This effort should be bipartisan.
The House hasn’t voted since SEPTEMBER 19TH, and now Speaker Johnson is canceling votes again next week. It'll be a full month without voting on time-sensitive issues like protecting ACA tax credits, lowering costs for American families, and paying our military, TSA, and air traffic controllers.
Speaker Johnson keeps changing his story about when Rep.-elect Grijalva will be sworn in. But here’s what we know for sure: once she takes the oath the Epstein file petition will hit 218 signatures, forcing a vote on the House floor. Why is Speaker Johnson postponing the inevitable?
#FactCheckFriday: If the White House read the law they’d know that undocumented immigrants can’t get federal healthcare benefits. This fight is about ensuring Americans don't see their monthly healthcare premiums double.
While Republicans push harmful cuts, Democrats are standing strong to protect your healthcare and fight for expanded access to quality, affordable care for everyone, no matter where you live.
Rural communities will be hit hardest by the loss of healthcare access. In places like Lake County, we’re already seeing critical medical healthcare projects shut down—direct consequences of the Big, Ugly Bill and the looming threat to ACA tax credits.
I stand with @gomez.house.gov in calling for the immediate release of Emily Wilder—a journalist and former Press Democrat reporter—who was detained by Israeli authorities while reporting on a humanitarian flotilla bound for Gaza. buff.ly/UXYVJHo
Even in the middle of a government shutdown, our servicemembers are still out there protecting our freedoms. Their courage never takes a break and neither should their paychecks. I called on the Speaker to bring back the House so we can ensure our troops are paid.
