Military and intelligence officers told spellbound lawmakers Tuesday that their careers had been ruined by superiors because they refused to lie about Able Danger, Abu Ghraib and other national security controversies. Lt. Col. Anthony Shaffer ... told a House Government Reform subcommittee that he and other intelligence officers and contractors working on the top-secret program code-named Able Danger" had identified Mohammed Atta, ringleader of the Sept. 11 attacks, but were prevented from passing their findings to the FBI. "Many of us have a personal commitment to ... going forward to expose the truth and wrongdoing of government officials who, before and after the 9/11 attacks, failed to do their job." Shaffer contradicted recent statements by Philip Zelikow, former executive director of the Sept. 11 commission, who denied having met with Shaffer and other Able Danger operatives in Afghanistan in October 2003. "I did meet with him," Shaffer said. "I have the business card he gave me. I find it hard to believe that he could not remember meeting me." The commission's chairman and vice chairman, former New Jersey Gov. Thomas Kean and former Rep. Lee Hamilton, released a statement saying the panel had looked into the work of Able Danger and found it "historically insignificant."
