George Tenet, on his website, calls Patrick Tyler's allegations "ludicrous:"

Tyler approached me in June of 2007 with this bogus story. 
Initially he told me that his sources told him that I was allegedly
staying at Prince Bandar's home in Riyadh alone when the
supposed incident happened.  I informed him that I had never
stayed at Bandar's home alone and on the date in question was
accompanied by two senior U.S. intelligence officials and my full
contingent of security staff.

I arranged for both of the senior officials, Scott Muller (the then-
General Counsel of the CIA) and Rob Richer (the then-Chief of
CIA's Near East Division) contact Tyler.  They both informed
Tyler, as I had previously said, that they were with me that
evening and no such incident happened.
