In a strongly worded letter, Senate Judiciary Committee chairman Chuck Grassley (R-IA) demanded that professor Christine Blasey Ford’s lawyers provide the committee with more evidence — including notes from therapy and polygraph documents — in light of her ex-boyfriend’s claims.

The ex-boyfriend in question, who is keeping anonymous, tried to cast doubt on Blasey Ford’s testimony in a number of ways, including saying that she had in her past “explained in detail what to expect, how polygraphs worked, and helped [a friend] become familiar and less nervous about the exam.”

Blasey Ford said during her testimony that she has never given any “tips” or “advice” to anyone taking a polygraph test.

In his letter, Grassley said that the different accounts raise “specific concerns about the reliability of her polygraph results.”

Grassley is also requesting the notes from couples therapy Blasey Ford was in with her husband in 2012, during which he says she talked about the alleged assault. Blasey Ford’s lawyers have reportedly held the notes back due to the “highly sensitive” nature of the information.

Grassley ends his letter by berating the lawyers for providing information to news outlets instead of the committee, saying “that the Senate is not a court of law does not change the reality that Dr. Ford’s allegations have put Judge Kavanaugh on trial before the nation.”
