Phillip Carter helped found Iraq and Afghanistan Veterans of America after a tour of duty advising the Iraqi police in Baqubah. He wrote amicus briefs in two Supreme Court cases, FAIR v. Rumsfeld and Hamdan v. Rumsfeld, where the Court reined in the Bush Administration’s executive over-reach, and became a leading critic of their methods in the war on terror. When he was hired by the Defense Department in April to coordinate detainee policy and help with the closure of the Guantanamo Bay prison camp, civil liberties groups considered that the Obama Administration was moving in the right direction.

He abruptly resigned late last week.
