Why would Cheney hide proposed Al Qaeda hit squads from congress?

The New York Times is reporting that the super-secret program Dick Cheney ordered the CIA to conceal from Congress involved a plan to send teams of hit men to hunt down suspected al Qaeda operatives.

We're told that job was ultimately left to killer drones because death squads proved impractical.

But if that was it, why would Dick Cheney order the CIA deny the program? The U.S. declared war on AQ after 9/11. The CIA has been operating against AQ ever since. You don't have to be a high-ranking intel committee member to know about the drone strikes, you just have to read a newspaper once in a while. Of course, Cheney is notoriously paranoid and secretive. But the administration even sends out press releases about its shiny killer drones.

A former CIA counterterrorism official told TPM Muckraker that there's no legal difference between killing with a drone and shooting or stabbing the victim.

So, it seems safe to assume that the program involved something more than a vague plan to send CIA agents to hunt down suspected terrorists in Afghanistan, or even Pakistan.
