Louisiana Republican Sen. Bill Cassidy said Tuesday that a criminal referral should be issued to the FBI to investigate Julie Swetnick, the third woman to accuse Supreme Court nominee Brett Kavanaugh of sexual misconduct.

A criminal referral should be sent to the FBI/DOJ regarding the apparently false affidavit signed by Julie Swetnick that was submitted to the Senate by @MichaelAvenatti. — U.S. Senator Bill Cassidy, M.D. (@SenBillCassidy) October 2, 2018

Swetnick, 55, alleged in a declaration submitted under oath to the Senate Judiciary Committee on Sept. 26 that she witnessed Kavanaugh spike girls’ drinks at high school parties.

Swetnick, who is being represented by attorney Michael Avenatti, also alleged that she saw Kavanaugh waiting in line to have group sex with girls at the parties. Swetnick further claimed that she was gang raped at a party, though she did not accuse Kavanaugh of taking part.

Swetnick had already graduated high school during the time period she says the incidents occurred.

Kavanaugh has vehemently denied all of the allegations. He has called Swetnick’s claims a “farce.”

Swetnick’s credibility has been called into question, and she has failed to produce eyewitnesses to back up her story.

Swetnick provided NBC News with the names of four people she claimed could corroborate her story. But the network reported on Monday that one of the people said they did not know Swetnick. Another alleged eyewitness was deceased and the other two could not be reached.

An ex-boyfriend of Swetnicks’ claimed that she threatened to kill him and his family after they broke up in 2001.

Swetnick was also accused by a former employer, Webtrends Inc., of making sexually suggestive remarks in business meetings with male colleagues. Webtrends sued Swetnick for making defamatory comments about her colleagues. (RELATED: Former Employer Sued Third Kavanaugh Accuser For Sexual Harassment Allegations)

After Cassidy sent his tweet, the Senate Judiciary Committee released a letter by a former Washington, D.C.-area TV weatherman named Dennis Ketterer, who claims to have met Swetnick in the early 1990s. Ketterer said that Swetnick told him that she liked group sex with multiple men.

He also said Swetnick claimed to have first tried group sex when she was in high school. Additionally, Ketterer said Swetnick never claimed to have been raped or assaulted.
