THE HILL: It’s WWIII Between CIA, Senate: Senators Alarmed By Alleged CIA Spying On Committee.

Senators on Wednesday expressed alarm at explosive allegations that the CIA might have spied on their computers to keep tabs on their controversial review of Bush-era “enhanced interrogation” techniques.

Lawmakers from both parties said that if the allegations against the CIA prove true, intelligence officials might have violated the law — and certainly violated the separation of powers enshrined in the Constitution.

“I’m assuming that’s it’s not true, but if it is true, it should be World War III in terms of Congress standing up for itself against the CIA, ” Sen. Lindsey Graham (R-S.C.) told The Hill.

Intelligence Committee Chairwoman Dianne Feinstein (D-Calif.) confirmed Wednesday that the CIA inspector general was investigating accusations that the covert agency had peered into the panel’s computers. But she didn’t comment on reports that the investigator has referred the matter to the Justice Department.

Senate Armed Services Committee Chairman Carl Levin (D-Mich.), an ex officio member of the Intelligence panel, said the charge of spying is “extremely serious.”

“There are laws against intruding and tampering, hacking into, accessing computers without permission. And that law applies to everybody,” he said.

Brennan in a statement said he was “dismayed” by the “spurious allegations,” which he said were “wholly unsupported by the facts.”

His statement was released Wednesday evening as McClatchy reported that the computer spying was allegedly discovered when the CIA confronted the Senate Intelligence panel about documents removed from the agency’s headquarters.

If the CIA was spying on its own oversight committee — with the President’s knowledge — that’s much worse than Watergate. And if there was this kind of illegal spying going on, what else was there?
