The President’s healthcare plan fails to help families struggling with spiking healthcare premiums. Health savings accounts aren’t a substitute for insurance when a loved one has a heart attack or cancer.
My Santa Rosa district office is experiencing issues with our phones that are expected to be addressed by the end of the day on Tuesday, January 20. If you are in need of assistance, please call my Napa district office at (707) 226-9898 or my Woodland district office at (530) 753-3501.
The bipartisan war powers resolution I coauthored to stop this President from dragging us into a war for oil in Venezuela could come up for a vote next week. This is important. We will not send our service members into harm's way in Venezuela, Greenland, or anywhere else for oil.
If you need help with passports and visas, veterans benefits, IRS issues, agricultural issues, small business assistance, immigration, Medicare and Medicaid, or if you are facing any other problem navigating the federal government, my team is ready to help.
I don’t trade or own stocks because public service should never be about personal profit. The American people need to know their representatives are working for them, not corporate interests. That’s why I signed the petition to force a vote to ban stock trading by members of Congress.
Mental health and substance use services save lives. When the administration said they were terminating these grants, we spoke out and pushed back. Because of pressure from Congress and the public, those funds were reinstated. I’ll never stop fighting to protect mental health care.
The Big Ugly Law ripped $1 trillion out of health care, and then a majority of Congressional Republicans refused to extend health care tax credits that lower costs for Americans. They’re defunding licensed providers like Planned Parenthood, which serves more than 2 million patients each year.
Joined @repmcgovern.bsky.social and Rep. Massie’s bipartisan war powers resolution to end this president’s military intervention in Venezuela. We won’t allow this president to put our military members in harm’s way for oil.
The President of the Farm Bureau is calling this the “toughest farm economy we’ve seen in a generation.” The economic pain across ag community is real, and it’s being made worse by Trump-era trade policies, tariffs, and economic uncertainty. Farmers shouldn’t be collateral damage of bad policy.
