Washington (CNN) Christine Blasey Ford's attorneys sent a letter Tuesday to FBI Director Christopher Wray requesting a call, saying they "have received no response" from anyone involved in the supplemental background investigation of Supreme Court nominee Brett Kavanaugh.

The letter, addressed to Wray and and FBI general counsel Dana Boente and obtained by CNN, says Ford's attorneys have offered her "full cooperation, including her willingness to be interviewed by FBI agents," but have received no response.

Ford has accused Kavanaugh of physically and sexually assaulting her at a party while they were in high school. He vehemently denies the allegation.

The letter notes it has been five days since the Senate Judiciary Committee and the White House announced that the FBI had been directed to conduct the supplemental investigation, following Kavanaugh's and Ford's testimony before the committee Thursday about her allegation.

"We also sent you a series of emails and letters," the letter reads, "in which we identified witnesses and evidence that would likely assist the FBI in its investigation into Mr. Kavanaugh's sexual assault of Dr. Ford and asked you to forward them to the supervisory agent."
