 McCain insists this issue overrides politics.McCain, whose 5 and one half years of captivity and torture in Vietnam made him a national celebrity, negotiated (in September 2006) a compromise in the Senate for the Military Commissions Act of 2006, suspending habeas corpus provisions for anyone deemed by the Executive Branch an "unlawful enemy combatant" and barring them from challenging their detentions in court.Coming on the heels of a Supreme Court decision adverse to the White House, McCain's compromise gave a retroactive, nine-year immunity to U.S. officials who authorized, ordered, or committed acts of torture and abuse, and permitted the use of statements obtained through torture to be used in military tribunals so long as the abuse took place by December 30, 2005.
