Deborah Ramirez, a Yale University classmate of Supreme Court nominee Brett Kavanaugh, is refusing to talk to the Senate Judiciary Committee about her accusation against Kavanaugh, a GOP lawmaker said Tuesday.

Ramirez lawyer John Clune tweeted Tuesday that “We have been working hard to cooperate with the Senate Judiciary Committee…and they have refused to meet all scheduled appointments.” He said Ramirez wants an FBI investigation, not a congressional investigation, and is willing to “swear to the FBI under penalty of perjury.”

A top Judiciary Committee GOP aide told the Washington Examiner in response to the Clune claim, “The Ramirez legal team has declined to comply with the committee’s established process and investigation and seem to prefer working through the media.“
