 Batarfi's document was 15 pages long, signed by Admiral Mark H Buzby, and dated April 29, 2008.During his appearance before Congress, Congressional Representative Frank Wolf, asked Brennan to explain why Batarfi had been cleared for release, when earlier military status reviews concluded there was reason to believe he had met Osama bin Laden, and that there was reason to believe he had played a role in an al Qaeda Weapons of Mass Destruction plan.In his written reply Brennan stated that the joint task force the Obama administration had put in place had conducted their own more recent review, and concluded the suspicions held against Batarfi weren't substantial enough to justify his detention.
