No recollection...or unwilling

CNN has learned that the committee has reached out to a longtime friend of Ford named Leland Ingham Keyser.

I understand that you have been identified as an individual who was in attendance at a party that occurred circa 1982 described in a recent Washington Post article," a committee staffer wrote Keyser earlier this week.

On Saturday night, her lawyer, Howard Walsh, released a statement to CNN and the Senate Judiciary Committee.

"Simply put," Walsh said, "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."

Ford's lawyer Debra Katz said in response to Keyser's attorney's statement that it makes sense that Keyser wouldn't remember, because Ford has said she did not share her allegations "publicly or with anyone for years."

It's not surprising that Ms Keyser has no recollection of the evening as they did not discuss it," Katz said in a statement. "It's also unremarkable that Ms. Keyser does not remember attending a specific gathering 30 years ago at which nothing of consequence happened to her."

In addition, Patrick J. Smyth issued a statement. "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 said 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."

"Personally speaking, I have known Brett Kavanaugh since high school and I know him to be a person of great integrity, a great friend, and I have never witnessed any improper conduct by Brett Kavanaugh towards women. To safeguard my own privacy and anonymity, I respectfully request that the Committee accept this statement in response to any inquiry the Committee may have."

I expect most of those people are Republicans of a certain financial situation (well above average), and wouldn't expect much, if any, corroboration for Ford,even if they do remember such a party and such an incident.  And the men probably don't want their own past during that time to be looked into.

...but hey, do what you want...you will anyway.
