SACRAMENTO, Calif. (AP) — In a stunning political reversal, prominent supporters of Rep. Eric Swalwell’s campaign for California governor withdrew their support Friday after the congressman denied allegations that he sexually assaulted a woman twice, including when she worked for him.

Swalwell did not immediately heed those calls, saying on social media that he would spend the weekend with family and friends and share an update “very soon.”

“These allegations of sexual assault are flat false. They’re absolutely false. They did not happen, they have never happened, and I will fight them with everything that I have,” he said.

Swalwell was among the leading Democrats in the race to replace outgoing Gov. Gavin Newsom. But in just hours, he saw his most prominent supporters — including U.S. Sen. Adam Schiff and powerful labor unions — drop their endorsements and call for his exit from the race.

Newsom, a likely 2028 presidential candidate who has avoided engaging in the contest to replace him, said in a statement: “As we continue to learn more, these allegations from multiple sources are deeply troubling and must be taken seriously.”
