The counsel of the conservative organization representing Brett Kavanaugh on Wednesday said that the FBI should have probed Christine Blasey Ford's sexual assault allegations against the Supreme Court nominee before they were revealed to the press.

"I agree, they should have investigated this," Carrie Severino told Hill.TV's Krystal Ball and Buck Sexton when asked why the FBI did not investigate the allegations. "That was when the allegations became known by the Senate Democrats. Senator [Dianne] Feinstein [D-Calif.] sat on Dr. Ford's allegations for six weeks."

It was revealed earlier this month that Feinstein, the ranking Democrat on the Senate Judiciary Committee, had passed a confidential letter to the FBI containing information about possible sexual misconduct involving Kavanaugh when he was in high school.

Christine Blasey Ford then went public with his allegations against Kavanaugh to the Washington Post.

The FBI confirmed that the information was added to a background file on the Supreme Court nominee put together at the White House's request.

Severino told Hill.TV that the leaked information on the letter jeopardized the opportunity for the bureau to probe the claims.

"That's what the FBI is for. Is she anonymous now? No. What happened is Democrat staffers because they were the only ones who had these allegations leaked it to the press. You don't go first to the press, and have them do the investigation," she said.

"The whole purpose of the FBI doing it is so they can actually do this in a way that is going to preserve everyone's confidentiality. Obviously, that's out of the bag. They have no opportunity anymore to interview witnesses in a responsible way," Severino continued. "You don't put the story out in the press, have them all read it, and then try to lines their things up with the story. There's no reliable witnesses anymore."

Democrats and proponents of an FBI probe say an investigation is essential for senators to make a proper judgment on Kavanaugh's character.

They also argue there is a precedent for an FBI probe, citing the 1991 investigation into Anita Hill's sexual harassment allegations against then-Supreme Court nominee Clarence Thomas.

Kavanaugh is facing sexual assault allegations from Ford and Deborah Ramirez.

On Wednesday, more allegations surfaced from a client of attorney Michael Avenatti.

He and Ford are slated to testify before the Senate Judiciary Committee on Thursday, one day before the GOP-majority committee will vote on Kavanaugh.
