House Republicans have postponed a vote on a measure to end the U.S. role in the bombing of Libya over fears the resolution would pass. The proposal from Democratic Rep. Dennis Kucinich of Ohio cites the Obama administration’s apparent violation of the 1973 War Powers Act, which requires congressional approval for military action after 60 days. In a statement, Kucinich said, “I am disappointed that the President and leadership feel the need to buy even more time to shore up support for the war in Libya. It’s not surprising that some are now wondering if a preliminary vote count…came out in favor of defending the Constitution.”
