The War Powers Act requires that the president notify Congress within 48 hours of offensive action against a foreign nation. So, Hussein has to serve Congress notice no later than 2:00pm EST Monday.
I think Congress is gone on spring break. Am I wrong?
I see your point. But the War Powers Act was meant to give the President some flexibility when the US was under attack or under immediate threat of attack.
Neither is the case with Libya. This is just another example of the elites casually ignoring the Constitution.
