Rep. Eric Swalwell — who’s running for Governor of California — has been accused of sexual assault by a former staffer … this according to a new report.

According to the San Francisco Chronicle, a woman, who says she had sexual encounters with the congressman while she worked for him, claims he sexually assaulted her twice … when she was too intoxicated to give consent.

Swalwell called the allegations “false” and threatened “legal action” in a statement on Friday, saying … “For nearly 20 years, I have served the public — as a prosecutor and a congressman and have always protected women.”

This accusation comes after social media speculation of Swalwell’s alleged misconduct against staffers. The congressman canceled a Palm Desert town hall Thursday night … claiming he was sick.
