WASHINGTON - A former FBI agent says the CIA has demanded cuts in his book on the 2001 terrorist attacks against the United States because it fears embarrassment. Ali Soufan, a Lebanese-American who spent years on counterterrorism, called the CIA's cuts "ridiculous," The New York Times reported Saturday. The FBI has already cleared his book, "The Black Banners: The Inside Story of 9/11 and the War Against al-Qaeda." "It saddens me that some are refusing to address past mistakes," Soufan said in a statement. Soufan's lawyer, David Kelley, in a letter to the counsel for the FBI, Valerie Caproni, said "credible sources" had told him the CIA hoped to stop publication because the book would be "embarrassing to the agency."
