Swalwell, who had been a candidate for governor of California, announced his decision in a statement posted to his account on X.

“I am deeply sorry to my family, staff, and constituents for mistakes in judgment I’ve made in my past. I will fight the serious, false allegation made against me. However, I must take responsibility and ownership for the mistakes I did make,” Swalwell said in the statement.

Swalwell’s troubles escalated rapidly over the weekend as reports in the San Francisco Chronicle and CNN detailed allegations from four women, including a former staff member who said he sexually assaulted her twice while she was too intoxicated to consent.

Swalwell had suspended his gubernatorial campaign over the weekend.
