Senate Judiciary Committee Chairman Chuck Grassley on Friday referred a woman who'd accused Supreme Court Justice Brett Kavanaugh of raping her “several times” in the backseat of a car to the Justice Department for “materially false statements” and “obstruction.”

Kavanaugh, confirmed to the high court on Oct. 6, was infamously accused by multiple women of sexual assault and misconduct before the confirmation.

Judy Munro-Leighton, according to Grassley’s office, “alleged that Justice Kavanaugh and a friend had raped her ‘several times each’ in the backseat of a car.”

Those accusations were made via a "Jane Doe" letter provided to Sen. Kamala Harris, a California Democrat and committee member, Grassley’s office wrote.

Upon further investigation, however, inconsistencies in the story emerged.

“Given her relatively unique name, Committee investigators were able to use open-source research to locate Ms. Munro-Leighton and determine that she: (1) is a left-wing activist; (2) is decades older than Judge Kavanaugh; and (3) lives in neither the Washington DC area nor California, but in Kentucky,” Grassley’s office wrote.

“Under questioning by Committee investigators, Ms. Munro-Leighton admitted, contrary to her prior claims, that she had not been sexually assaulted by ... Kavanaugh and was not the author of the original 'Jane Doe’ letter,” Grassley’s office wrote in a Friday referral to the DOJ.

“When directly asked by Committee investigators if she was, as she had claimed, the ‘Jane Doe’ from Oceanside California who had sent the letter to Senator Harris, she admitted: ‘No, no, no. I did that as a way to grab attention. I am not Jane Doe . . . but I did read Jane Doe’s letter. I read the transcript of the call to your Committee. . . . I saw it online. It was news.”

“In short, during the Committee’s time-sensitive investigation of allegations against Judge Kavanaugh, Ms. Munro-Leighton submitted a fabricated allegation, which diverted Committee resources. When questioned by Committee investigators she admitted it was false, a ‘ploy,’ and a ‘tactic,’” Grassley’s office wrote. “She was opposed to Judge Kavanaugh’s confirmation.”

Friday’s referral to the DOJ was not the first time Grassley has asked for an investigation into Kavanaugh’s accusers.

Last week, Grassley referred attorney Michael Avenatti and client Julie Swetnick -- who'd accused Kavanaugh of sexual misconduct -- for criminal investigation regarding a potential “conspiracy” to provide false statements to Congress and obstruct its investigation.

Avenatti is also a potential 2020 Democratic presidential candidate and works as the attorney for adult film star Stormy Daniels, who maintains she had a sexual encounter with President Trump years before his election. Avenatti represented Swetnick, who accused Kavanaugh during confirmation proceedings of being involved in or present at “gang” and “train” rapes at high school parties in the 1980s.

Kavanaugh denied all the claims against him.
