Rep. Eric Swalwell dropped his bid for governor of California days after a former aide accused him of sexually assaulting her. The Democratic candidate faced immediate calls to end his campaign, with many supporters withdrawing their endorsements.

"To my family, staff, friends, and supporters, I am deeply sorry for mistakes in judgment I've made in my past. I will fight the serious, false allegations that have been made — but that's my fight, not a campaign's," he wrote on social media.
