Attorney general chides ruling

"But this view is shortsighted," he said. "Its definition of freedom -- one utterly divorced from civic responsibility -- is superficial and is itself a grave threat to the liberty and security of the American people."

Gonzales and Cheney's attacks on the court order came as the administration was urging the lame-duck Congress to approve legislation authorizing the warrantless surveillance. The bill's chances are in doubt, however, because of Democratic opposition in the Senate, where 60 votes are required to end debate and vote.

At a news conference, Gonzales would not speculate how the administration would react if Congress did not authorize warrantless surveillance.

"We're optimistic because of the importance of this program, the success of the program, the stated commitment of the Democratic leadership to work with us in protection of America, and that we're going to have a good discussion and dialogue about the program," he said.

"We believe the president has the authority under the authorization of military force and inherent authority of the Constitution to engage in this sort of program, but we want to supplement that authority," he said.

The administration has maintained that its warrantless surveillance program focuses on international calls involving suspected terrorists and dismisses charges that it is illegal.
