Two years ago today, five people were tragically killed by a shooter at Louisville’s Old National Bank. Today, we remember those whose lives were cut short and honor their memory by continuing our work to make our communities safer.
Our U.S. Trade Representative spent two hours testifying before our committee today to tell us how tariffs are needed. Then, the President pulled the plug while he was testifying — he heard it for the first time when we heard it!  The President has no plan.
The President’s tariffs are costing families an extra $3,800 per year and upending foreign markets for American businesses and ag producers. U.S. Trade Representative Jamieson Greer had no answers for the Ways & Means Committee today on how our economy can afford this $6T tax hike. bit.ly/42Cf5yd
Proud to have voted to pass a bill to fund research and treatment of certain cancers connected to veterans’ time serving in the Vietnam War, including exposure to liver fluke. As a Vietnam vet myself, I know how critical it is to have access to care when you need it.
These cuts will force hospitals and community health centers to slash services or close their doors. This will mean fewer doctors, longer waits, and less access to care for everyone, whether you're on Medi-Cal or not.
One in three Californians rely on Medi-Cal for their health care, yet Congressional Republicans’ are planning cuts to the program to pay for tax breaks for people well-off enough that they don't need the help.
Proud to introduce the Mental Health Research Accelerator Act with Rep. Mike Kelly. We need to stop treating mental health like an afterthought. This bill invests $10 billion in tax credits over six years to drive research into the root causes of mental illness, not just the symptoms.
Rogue gun dealers give honest sellers a bad name and make our communities less safe. In a giveaway to the Washington gun lobby, the Trump Administration is reopening the pipeline gun traffickers use to get guns to criminals and other people who are a danger to themselves or others.
Senate Republicans just voted for the next step in their party’s plan to cut health care funding for hardworking Americans in order to give $6 trillion away in tax breaks for the ultra-rich.
FACT: The Wall Street Journal has corrected the record, stating: “In the real economic world, a tariff is a tax. If you raise $600 billion more a year in revenue for the federal government, you are taking that amount away from individuals and businesses in the private economy.”
57 years ago today, Dr. Martin Luther King, Jr was assassinated in Memphis, Tennessee for his influential role in the Civil Rights Movement. Today, we remember his legacy and continue to carry on his work for justice and equality.
