Matthew L. Wald, in the April 14, 2004, New York Times, wrote that the Panel had cleared the handling of the Bin Laden family on September 11th. 
The Commission determined that the Bush administration had properly handled the evacuation of the "six chartered flights that rushed scores of Saudi citizens out of the United States after the attacks."
"A flight on Sept. 20, 2001, carried 26 passengers, most of them relatives of Osama bin Laden, according to the statement. But all 142 passengers on the flights, mostly Saudi citizens, were screened by law enforcement officials, the statement said, to ensure that they were not security threats and not wanted for questioning. The flights were 'dealt with in a professional manner' by the government, the commission said.
"The rush by the Saudis to depart attracted notice and stirred accusations that the administration allowed it to take place to maintain good relations with the Saudis. An article in Vanity Fair magazine last October asserted that the Saudis were allowed by the White House to violate a ban on flights imposed after the attacks to fly a group from Tampa, Fla., to Lexington, Ky., in a small jet, where they would join a larger group. But the Federal Aviation Administration maintained that the ban was lifted before the plane took off.
"Among other critics, Senator Charles E. Schumer of New York said last September that some of the Saudis who were allowed to leave may have had ties to terrorism. 'This is just another example of our country coddling the Saudis and giving them special privileges that others would never get,' he said.
"But according to the statement, the FBI checked 'a variety of databases' and searched the aircraft. The statement said that it was not clear whether anyone checked a watch list maintained by the State Department, but that a check after the departure showed no matches.
"The statement said the FBI concluded that no one who was allowed to depart was wanted for questioning, and that the commission had found no evidence to contradict this."
