On Friday, U.S. Representative Mike Thompson (CA-04) was sworn in as a member of the United States House of Representatives by Speaker of the House Mike Johnson.

The swearing-in ceremony for Thompson and hundreds of other recently elected House members took place after Johnson was reelected as speaker.

“It’s the honor of my life to serve the people of the community where I was born, grew up, raised my own family and live today,” said Thompson. “Over the next two years, my priority will remain the same: To deliver for the constituents of the Fourth District. That includes working to lower costs, improve community safety, fight climate change, and protect your fundamental rights and freedoms.”

Thompson was reelected on Nov. 5 to serve California’s Fourth Congressional District, which includes all of Lake and Napa counties, and parts of Solano, Sonoma and Yolo counties.

An Army veteran who reached the rank of staff sergeant in the 173rd Airborne Brigade and received the Purple Heart while serving in Vietnam, he became the first Vietnam veteran elected to the California Senate in 1990.

Thompson then ran successfully in 1998 for Congress, where he has served ever since.

On Friday, he was once again added to the rolls of the House upon executing the oath of office.

Thompson, a Democrat, is a senior member of the House Committee on Ways and Means, chairman of the House Gun Violence Prevention Task Force, co-chair of the bipartisan, bicameral Congressional Wine Caucus and a member of the fiscally-responsible Blue Dog Coalition.
