What about the 3 other witnesses that Dr. Ford named in her letter that later said they weren't there and it never happened?
That's not quite what they said:
Leland: "Simply put, Ms. Keyser does not know Mr. Kavanaugh and she has no recollection of ever being at a party or gathering where he was present, with, or without, Dr. Ford" [statement from lawyer]
PJ: "I understand that I have been identified by Dr. Christine Blasey Ford as the person she remembers as 'PJ' who supposedly was present at the party she described in her statements to the Washington Post," Smyth says in his statement to the Senate Judiciary Committee. "I am issuing this statement today to make it clear to all involved that I have no knowledge of the party in question; nor do I have any knowledge of the allegations of improper conduct she has leveled against Brett Kavanaugh." [Keep in mind he had written a letter supporting Kavanaugh in the summer FWIW]
Judge's latest statement: "I don't recall" the event in question; "I have never seen Brett act in a manner as described by Ford". Might be a biased witness.
I'm curious about "Squi"...haven't seen any statement as to whether he was there, not has Ford confirmed it...which means it's hard to say whether the July 1 event in Kavanaugh's calendar could be the event she described.
