(AP) — Democratic Rep. Eric Swalwell of California announced Monday he will resign from Congress following multiple assault allegations that prompted loud bipartisan calls for him to step down.

The decision caps a swift political fall for the seven-term lawmaker, who had been seen as a frontrunner in California’s gubernatorial race before dropping out as the allegations surfaced, claims he has continued to deny.

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