Check the last paragraph of the letter particularly. Grassley’s letter dropped last night and people wondered what dirt he had on them. Now, here’s part of the answer, but obviously, he knows more. Note the specific mention of contact with Mazie Hirono.

On Thursday, Senator Charles Grassley, Chairman of the Judiciary Committee, sent a searing letter to the attorneys representing Christine Blasey Ford, who has accused Judge Brett Kavanaugh of sexually assaulting her in 1982. Grassley reiterated his already twice-stated request for the attorneys to turn over the “therapy notes, polygraph materials, and communications with The Washington Post that Dr. Ford has relied upon as evidence.”
Grassley began by noting that as the Senate is charged by the Constitution to advise the president on his nominees for the Supreme Court, the Committee had a “constitutional obligation to investigate and evaluate independently the President’s nominees.” He pointed out that the Senate’s “obligation is unrelated to anything the FBI does … We have to make our own assessment.”
