A former Democratic candidate for Congress has raised new questions about Supreme Court nominee Brett Kavanaugh’s accuser Julie Swetnick’s credibility by saying she has “psychological” problems.

Dennis Ketterer, a former weatherman for WJLA Channel 7 in Washington, sent a signed statement to the Senate Judiciary Committee Tuesday claiming that Swetnick had psychological problems and liked to engage in sexual intercourse with more than one male partner at the same time.
