WASHINGTON, Oct. 5 — President Bush, reacting to a Congressional uproar over the disclosure of secret Justice Department legal opinions permitting the harsh interrogation of terrorism suspects, defended the methods on Friday, declaring, “This government does not torture people.”

The remarks, Mr. Bush’s first public comments on the memorandums, came at a hastily arranged Oval Office appearance before reporters. It was billed as a talk on the economy, but after heralding new job statistics, Mr. Bush shifted course to a subject he does not often publicly discuss: a once-secret Central Intelligence Agency program to detain and interrogate high-profile terror suspects.

“I have put this program in place for a reason, and that is to better protect the American people,” the president said, without mentioning the C.I.A. by name. “And when we find somebody who may have information regarding a potential attack on America, you bet we’re going to detain them, and you bet we’re going to question them, because the American people expect us to find out information — actionable intelligence so we can help protect them. That’s our job.”

Without confirming the existence of the memorandums or discussing the explicit techniques they authorized, Mr. Bush said the interrogation methods had been “fully disclosed to appropriate members of Congress.”
