Former U.S. Sen. Bob Graham has accused the FBI in court papers of having impeded Congress's Joint Inquiry into 9/11 by withholding information about a Florida connection to the ... attacks that killed nearly 3,000 people. The information ... includes a recently declassified FBI report that ties a Saudi family who once lived in Sarasota to individuals associated with the terrorist attacks on 9/11/2001." "The FBI's failure to call (to the Joint Inquiry's attention) documents finding 'many connections' between Saudis living in the United States and individuals associated with the terrorist attack(s) interfered with the Inquiry's ability to complete its mission," said Graham, co-chairman of the Joint Inquiry. Graham said the FBI kept the 9/11 Commission in the dark, too. He said co-chairmen Thomas Kean and Lee Hamilton and executive director Philip Zelikow all told him they were unaware of the FBI's Sarasota investigation. Moreover, Graham stated that Deputy FBI Director Sean Joyce, the Bureau's second in command, personally intervened to block him from speaking with the special agent-in-charge of the Sarasota investigation. "I am troubled by what appears to me to be a persistent effort by the FBI to conceal from the American people information concerning possible Saudi support of the Sept. 11 attacks," Florida's former governor said.
