More Pre-Attack Tips Surface

(CBS) The chairman of the Senate Intelligence Committee said Sunday "significant numbers of people" from inside the government were coming forward with new information on U.S. intelligence failures related to the Sept. 11 attacks on America.

Sen. Bob Graham, a Florida Democrat, said some of those offering information to the joint investigation of the Senate and House intelligence committees were emboldened by the recent disclosures of FBI whistle-blower Coleen Rowley. He also said it was becoming clear "there are some people who deserve to get sanctions as a result of what they were doing before Sept. 11."

"We are already getting significant numbers of people coming to us, either in person or with materials that hadn't previously been known," Graham told CBS' "Face the Nation" program. "I think the testimony of Ms. Rowley has given encouragement to folks" inside the federal bureaucracy.

Sen. Richard Shelby, the ranking Republican on the Senate Select Committee on Intelligence, said such failures extended beyond the FBI and CIA to the super-secret National Security Agency and elsewhere.

Shelby also said the sweeping plan for a new Department of Homeland Security proposed last week by President

Bush did not effectively address the failures of intelligence-gathering uncovered so far.

In a stinging letter to FBI Director Robert Mueller, Rowley questioned his handling of information and accused FBI headquarters of hampering field agents from fully investigating Zacarias Moussaoui, the man officials now believe intended to become the 20th hijacker in the Sept. 11 attacks.
