Rep. Dennis Kucinich (D-OH) took criticism of Obama's Libya intervention to a whole new level Monday, suggesting that the president’s decision “would appear on its face to be an impeachable offense” in an interview with Raw Story. "President Obama moved forward without Congress approving. He didn't have congressional authorization, he has gone against the Constitution, and that's got to be said," added Kucinich in the interview. "It's not even disputable, this isn't even a close question. Such an action—that involves putting America's servicemen and -women into harm's way, whether they're in the Air Force or the Navy—is a grave decision that cannot be made by the president alone." Of course, several past U.S. presidents have engaged in military conflicts without congressional approval, such as President Clinton’s air attacks on Serbia in 1999 and President Reagan’s attacks on the Gaddafi regime in 1986. The War Powers Act requires that Obama must request congressional approval for committing U.S. forces abroad within 60 days.
