What Gonzales will say about the surveillance program.

Today, Attorney General Gonzales will testify before the Senate Judiciary Committee about the Bush administration's surveillance program. He's got a column in the WSJ this morning, which presumably reflects what he will say:

The president, as commander in chief, has asserted his authority to use sophisticated military drones to search for Osama bin Laden, to deploy our armed forces in combat zones, and to kill or capture al Qaeda operatives around the world. No one would dispute that the [The Authorization for Use of Military Force] supports the president in each of these actions.

It is, therefore, inconceivable that the AUMF does not also support the president's efforts to intercept the communications of our enemies. Any future al Qaeda attacks on the homeland are likely to be carried out, like Sept. 11, by operatives hiding among us. The NSA terrorist surveillance program is a military operation designed to detect them quickly. Efforts to identify the terrorists and their plans expeditiously while ensuring faithful adherence to the Constitution and our existing laws is precisely what America expects from the president....

The AUMF is broad in scope, and understandably so; Congress could not have catalogued every possible aspect of military force it was endorsing. That's why the Supreme Court ruled in Hamdi v. Rumsfeld that the detention of enemy combatants--a fundamental incident of war-- was lawful, even though detention is not mentioned in the AUMF. The same argument holds true for the terrorist surveillance program. Nor was the president's authorization of the terrorist surveillance program in violation of the Foreign Intelligence Surveillance Act. FISA bars persons from intentionally "engag[ing] . . . in electronic surveillance under color of law except as authorized by statute." The AUMF provides this statutory authorization for the terrorist surveillance program as an exception to FISA.

Lastly, the terrorist surveillance program fully complies with the Fourth Amendment, which prohibits unreasonable searches and seizures. Like sobriety checkpoints or border searches, this program involves "special needs" beyond routine law enforcement, an exception to the warrant requirement upheld by the Supreme Court as consistent with the Fourth Amendment.

We already know this is the argument. We also know the argument of those who oppose the program. What will be interesting today will be to see how well Gonzales will be able to defend the program under hard questioning and how far the Senators will be willing to go when they know that part of the answer, explicit or insinuated, will inevitably be that if they oppose the program they do not care enough about national security.
