Congress defied a White House veto threat yesterday and voted to ban the CIA from using "waterboarding" and other harsh interrogation techniques.
On a largely party-line vote of 51-45, the Democratic-led Senate passed a broad intelligence measure approved in December by the House of Representatives and sent it to President George W. Bush.
"There must be no doubt in the world that this great nation does not torture," said Nebraska Republican Sen. Chuck Hagel, one of the bill's chief sponsors.
Waterboarding, a simulated drowning technique, has been condemned by human rights groups and other countries as torture and illegal.
But a White House spokesman said aides would recommend a Bush veto. "Parts of this bill are inconsistent with the effective conduct of intelligence gathering," he said.
Senator John McCain of Arizona, the leading Republican presidential candidate and an author of previous anti-torture legislation, voted against the overall intelligence bill.
The interrogation provision says the CIA must adhere to limitations in the US army field manual. "I made it very clear that I think that waterboarding is torture and illegal, but I will not restrict the CIA to only the army field manual," Mr McCain said before the vote.
The new provision would require the CIA to comply with army rules on questioning detainees, which forbid eight methods including waterboarding, forced nudity, electric shock, use of dogs and mock executions.
The legislators' move follows CIA director Michael Hayden's disclosure to Congress last week that government interrogators had used waterboarding on three suspects captured after the September 11th attacks.
