The Senate has agreed to give President Bush extraordinary power to detain and try prisoners in the so-called war on terror. The legislation strips detainees of the right to file habeas corpus petitions to challenge their own detention or treatment. It gives the president the power to indefinitely detain anyone it deems to have provided material support to anti-U.S. hostilities. Secret and coerced evidence could be used to try detainees held in U.S. military prisons. The bill also immunizes U.S. officials from prosecution for torturing detainees who the military and the CIA captured before the end of last year. The Senate passed the measure sixty five to thirty four. Twelve Democrats joined the Republican majority. The House passed virtually the same legislation on Wednesday. Legal groups, including the Center for Constitutional Rights, are already preparing to challenge the constitutionality of the law in court.
