Washington (CNN) As the Senate Judiciary Committee staff negotiates with attorneys for Christine Blasey Ford, the woman who has accused Supreme Court nominee Brett Kavanaugh of a past sexual assault, over a potential hearing on Thursday, Republican staffers are working to interview those who may have information about the alleged incident.

CNN has learned that the committee has reached out to a longtime friend of Ford named Leland Ingham Keyser.

"I understand that you have been identified as an individual who was in attendance at a party that occurred circa 1982 described in a recent Washington Post article," a committee staffer wrote Keyser earlier this week.

On Saturday night, her lawyer, Howard Walsh, released a statement to CNN and the Senate Judiciary Committee.
