Lawyers for Christine Blasey Ford say in a letter to FBI Director Chris Wray that they’ve received no response from anyone involved in the FBI’s reopened background investigation of Supreme Court nominee Brett Kavanaugh.

Ford, a California professor, has said she was sexually assaulted by Kavanaugh at a party when they were teenagers. He denies that allegation.

In a letter Tuesday to Wray and his general counsel, Ford’s lawyers say it is “inconceivable” that the FBI could conclude its investigation without interviewing either her, Kavanaugh or all of the other witnesses whose names she has provided.
