Prominent supporters of California Rep. Eric Swalwell's bid for governor are withdrawing their support Friday in a stunning political reversal. It comes after the congressman denies allegations that he sexually assaulted a woman twice, including once when she worked for him. The woman told her account to the San Francisco Chronicle. The AP hasn't been able to independently verify her account or identity. Swalwell has disputed the allegations, but now faces growing calls from prominent Democrats to drop out. The allegations surfaced weeks before mail ballots are scheduled go out in advance of a June 2 primary election.
