Memo on 9/11 Plotters Blocked

Memo on 9/11 Plotters Blocked:

"A chilling new detail of U.S. intelligence failures emerged Thursday, when the Justice Department disclosed that about 20 months before the Sept. 11 attacks, a CIA official had blocked a memo intended to alert the FBI that two known Al Qaeda operatives had entered the country.

The two men were among the 19 hijackers who crashed airliners into the World Trade Center, the Pentagon and a field in Pennsylvania.

An 18-month delay in the CIA's handing over of information about the two hijackers to the FBI and other domestic law enforcement agencies had been well-publicized. But the report's conclusion that an agent had written a memo specifically designed for transmittal to the FBI to alert the bureau to the men's presence — and that a supervisor deliberately had prevented it from being sent — is new.

The reason the CIA official, identified by the fictitious name 'John,' put a hold on the communique remains a mystery, the report said. It said the officials involved didn't recall the incident. Even when the author of the memo followed up a week later with an e-mail asking if it had been sent to the FBI, nothing was done."
