The revelation about Bandar's indirect ties to the al Qaeda operative was one of the few pieces of new information contained in the declassified documents.
The CIA and FBI concluded that there was no evidence anyone from the Saudi royal family knowingly provided support for the 9/11 attacks.
But Graham said the indirect connection to the respected former Saudi ambassador was "one of the most stunning parts of the investigation" and worthy of pursuing further.
Bandar was the Saudi ambassador to the United States from 1983 to 2005, during the Ronald Reagan, George H. W. Bush, Bill Clinton and George W. Bush administrations. He later served as secretary general of Saudi Arabia's National Security Council and head of Saudi Arabia's General Intelligence Presidency, the equivalent of the CIA, until last year.
Bandar "is probably the most effective ambassador in Washington ever. Full stop," said former CIA analyst Bruce Riedel. "He was highly regarded by every president."
Clinton, Bush, Reagan, Obama, all buddies with this guy it seems ---
