The FBI is expected to deliver a supplementary background check on Supreme Court nominee Brett Kavanaugh this afternoon, said Sen. Bob Corker, R-Tenn.

Corker told reporters after a closed-door GOP meeting that lawmakers were told a stack of interviews relating to sexual misconduct allegations against Kavanaugh would soon be available for them to review in a secure reading room in the basement of the Capitol.

"I think it may come up this afternoon," Corker said.

Corker said lawmakers were told in the meeting the FBI would not be providing any summary or findings but rather would deliver a stack of interviews, "where they went and talked to people," Corker said. "It's possible they may have conflicting accounts."

Senators review secure or classified documents in a room in the Capitol basement visitor center. Senators will not be provided individual copies, Corker said, and will have to review the documents in the room.

Corker said a first of two votes on Kavanaugh is anticipated on Friday and that Majority Leader Mitch McConnell could set that process in motion on Wednesday by filing cloture on the nomination.
