FILE - In this Sept. 13, 2001 file photo, an American flag flies over the rubble of the collapsed World Trade Center buildings in New York. For years, a handful of current and former American officials have been urging President Barrack Obama to release secret files that they believe document links between the government of Saudi Arabia and the terrorist attacks of September 11, 2001.
