Now he tells us

"I was going to obey the War Powers Act the whole time," says Obama.

Yeah right:

Facing criticism from Congress that authority for U.S. military action in Libya is about to expire under the War Powers Act, President Obama asked congressional leaders late Friday for a resolution of support for continuing the military involvement.
"It has always been my view that it is better to take military action, even in limited actions such as this, with congressional engagement, consultation and support," Obama wrote in a letter to the Democratic and Republican leaders of the House and Senate. "Congressional action in support of the mission would underline the U.S. commitment to this remarkable international effort."

Nick Gillespie:

On May 10, Foreign Policy reported "Senate has no plans to invoke War Powers Act over Libya," so if I were Speaker Boehner, I'd just go ahead and hit the links for the 1,000th time this spring. Sen. John "Reportin' for Duty" Kerry (D-Mass.) is the head of the Senate's Foreign Relations committee and he told FP that the War Powers Act wasn't in play because the U.S. is "deferring to NATO." (Side note: WTF? A decision to commit forces to NATO doesn't count as a deployment?) And Sen. Richard Lugar (R-Ind.) doesn't seem all bent out of shape either, though he's sad that all this other sh**t the government has failed to address has made it impossible to really think about anything at all.

The hypocrisy is astounding. The good little liberals in Congress who challenged every deployment of American troops since the Libyan bombing under Reagan has suddenly discovered that the War Powers Act doesn't apply?

So much for principle.
