Taps found clues, not Al Qaeda, FBI chief says

WASHINGTON - The National Security Agency's secret domestic spying hasn't nabbed any Al Qaeda agents in the U.S. since the Sept. 11 attacks, FBI Director Robert Mueller told Congress yesterday.

Mueller told the Senate Intelligence Committee that his agents get "a number of leads from the NSA," but he made it clear Osama Bin Laden's henchmen weren't at the end of the trail.

"I can say leads from that program have been valuable in identifying would-be terrorists in the United States, individuals who were providing material support to terrorists," Mueller testified.

His assessment of the controversial NSA snooping appeared to undercut a key claim by President Bush. As recently as Wednesday, Bush defended bypassing courts in domestic spying by insisting that "one of the people making the call has to be Al Qaeda, suspected Al Qaeda and/or affiliate."
