Sen. Chuck Grassley (R-Iowa), the chairman of the Senate Judiciary Committee, on Sunday released the confidential letter that Christine Blasey Ford sent to Democratic lawmakers accusing Supreme Court nominee Brett Kavanaugh of sexually assaulting her when they both were in high school.

The letter, along with a cover letter in which Sen. Dianne Feinstein (D-Calif.) writes that she expects Grassley to maintain confidentiality, was posted on the committee’s website.

“As you know, the letter was given to me in confidence and I am giving it to you with the expectation that you will maintain its confidentiality and that it will not be released publicly or disseminated further, as requested by Dr. Blasey Ford’s counsel Debra Katz,” Feinstein wrote in the cover letter.

Committee members wrote a separate post on the website:

“The Committee did not learn of the actual contents of the letter until CNN published a redacted version of the letter on September 17. We do not know who leaked this letter to the press, notwithstanding Dr. Ford’s request for confidentiality. Despite revelations of Dr. Ford’s identity, the Ranking Member and Dr. Ford’s attorneys to date still have not publicly released a copy of the original version of the letter or shared it more broadly than the 21 members and senior staff of the Judiciary Committee. The Chairman has repeatedly called for the public release of this hidden evidence.”

In the letter, Blasey identifies Mark Judge as the person she says assisted Kavanaugh the assault. His name was redacted from the version made public by CNN.

Feinstein has maintained that she did not disclose the letter, dated July 30, when she received it because Blasey had sent it to her in confidence.

Grassley also asked lawyers for both Kavanaugh and Blasey to provide “any and all written, audio-visual, or electronic materials” relating to the allegations. He also asked for the results of a polygraph that Blasey said she had taken in August.
