What the FBI Knew Before 9/11

W A S H I N G T O N, April 13 -- The independent commission charged with investigating 9/11 is now turning its attention to the FBI and apparent intelligence failures in the months before the attacks.

The commission is hearing testimony today from current and former intelligence officials, including former FBI Director Louis Freeh, former Attorney General Janet Reno and current Attorney General John Ashcroft.

The release of the president's daily intelligence briefing from Aug. 6, 2001, has raised new questions about the FBI's handling of the terrorist threat leading up to 9/11. The main question — what was the FBI doing in the summer of 2001?

The Bush administration has said there were 70 investigations conducted by FBI field offices looking for evidence of al Qaeda activity in the United States. But some members of the 9/11 commission said they could find no evidence to support that assertion.

"To date, we have found nobody — nobody at the FBI — who knows anything about a tasking of field offices," commissioner Tim Roemer, a former Democratic congressman from Indiana, said last week.

Sources tell ABCNEWS that senior FBI officials were 95 percent to 98 percent certain that an attack was coming, but did not believe it would occur in the United States.

Why Wasn’t Information Passed On?

Commissioners will want to find out why senior FBI officials were not aware of important information their field agents had developed, including a memo by Phoenix FBI Agent Ken Williams, describing suspected al Qaeda members training at U.S. flight schools.

This raises another question for 9/11 commissioner Richard Ben Veniste. "Why was there not an effort to pulse the FBI, to send a message throughout the FBI, 'Tell us everything that you got'?"

It's expected that the FBI will acknowledge it did not keep track of its own investigations — an admission officials have made before.
