The Senate defied a presidential veto threat nearly three weeks ago and approved, 90 to 9, an amendment to a $440 billion military spending bill that would ban the use of "cruel, inhuman or degrading treatment" of any detainee held by the United States government. This could bar some techniques that the C.I.A. has used in some interrogations overseas.
But in a 45-minute meeting last Thursday, Vice President Dick Cheney and the C.I.A. director, Porter J. Goss, urged Senator John McCain, the Arizona Republican who wrote the amendment, to support an exemption for the agency, arguing that the president needed maximum flexibility in dealing with the global war on terrorism, said two government officials who were briefed on the meeting.
Mr. McCain rejected the proposed exemption, which stated that the measure "shall not apply with respect to clandestine counterterrorism operations conducted abroad, with respect to terrorists who are not citizens of the United States, that are carried out by an element of the United States government other than the Department of Defense and are consistent with the Constitution and laws of the United States and treaties to which the United States is a party, if the president determines that such operations are vital to the protection of the United States or its citizens from terrorist attack."
