Defense Secretary Donald Rumsfeld announced yesterday that the Pentagon intends to move ahead quickly with the military trials of two prisoners at the Guantanamo prison camp and file charges against eight others. This comes after a ruling Friday by a three-judge federal appeals court panel. Rumsfeld said the ruling was a vindication of the Bush administration’s policy on prosecuting detainees. But lawyers for at least one of the prisoners said they will appeal the ruling, saying Bush violated the separation of powers in the Constitution when he established military commissions.
