The Department of Defense forbade a military intelligence officer to testify Wednesday about the work of a secret military unit that identified four 9/11 hijackers more than a year before the Sept. 11 terrorists attacks, according to the man's attorney.In written testimony prepared for the Senate Judiciary Committee hearing, attorney Mark Zaid, who represents Lt. Col. Anthony Shaffer, said the Pentagon also refused to permit testimony there by a defense contractor that he also represents.
The Judiciary Committee was scheduled to hear testimony about the work of a classified unit code named "Able Danger."
