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.
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.
To restore clean energy tax credits, lower costs for families, and ensure America leads the world in the clean energy economy. It’s time to bring energy prices down, boost U.S. manufacturing, and put America back in charge of our energy future.
Families shouldn’t have to pay more because Congressional Republicans rolled back clean energy incentives that were saving money and creating jobs. That’s why I led over 114 of my colleagues in introducing the American Energy Independence and Affordability Act

At American Canyon’s Wall That Heals ceremony, eight women’s names are etched on the wall — all nurses who served during the Vietnam War. Their courage matched that of every soldier on the battlefield.
Californians are getting notices from their insurers that their healthcare premiums are set to double and even triple due to the expiration of healthcare tax credits. We’re watching a trainwreck and Republican leadership is doing nothing about it. Speaker Johnson, bring back the House.
Congressional Republicans have no plan—just a political agenda that hurts hardworking families. While they refuse to come back to work, Democrats are in Washington fighting to keep healthcare affordable and government open for the people we serve.
Undocumented immigrants, who can’t even get healthcare tax credits under the ACA, and are regulated by the Department of Homeland Security, which Republicans also control. Democrats are here fighting for your healthcare.
Speaker Johnson, you sent a bill to the Senate 39 days ago that cannot muster the votes to pass. Bring back the Republicans, reconvene the House, and let’s do the work the American people sent us to do.
There are clear, established rules for any renovation of the White House. This President ignored them, demolishing the East Wing to build his ballroom. The White House represents more than any one person or administration — it’s a symbol of our shared history and democracy.
Celebrating Sheriff Tom Ferrara’s incredible career — more than 45 years of service to our community and over a decade leading the Solano County Sheriff’s Office. Thank you, Tom, for your integrity, leadership, and lifelong dedication to public safety.
Proud to welcome this year’s Student Leadership Council at UC Davis! I started the SLC eight years ago to give students the tools to lead — and today, our nearly 250 alumni are tackling the biggest challenges of our time, from climate change to strengthening our democracy.
