Rep. Eric Swalwell (D-Calif.) announced Sunday he is suspending his campaign for governor amid allegations of rape, sexual assault and sexual misconduct, which he denies.Why it matters: Swalwell was one of the Democratic frontrunners in the race. His exit is a colossal shakeup of what has already been one of the most volatile gubernatorial races in recent memory.What they're saying: "I am suspending my campaign for Governor," Swalwell wrote in a post on X."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."Between the lines: Swalwell offered no indication he plans to give up his House seat, amid calls from colleagues in both parties for him to resign.Rep. Anna Paulina Luna (R-Fla.) has said she plans to force a vote to expel Swalwell when the House returns to session this week, though that would require a two-thirds majority to pass.This is breaking news.
