WASHINGTON (AP) -- President Barack Obama on Wednesday dismissed the congressional criticism of his decision to wage war against Libya as political and argued that any sign of support from Washington for strongman Moammar Gadhafi makes no sense. Pushing back against Republicans and Democrats, Obama defended his decision to order U.S. military action more than three months ago and insisted he had not violated the 1973 War Powers Resolution, which requires congressional authorization within 60 days of the first military strikes. The president claims Americans supporting the NATO-led operation are not engaged in full-blown hostilities, making congressional consent unnecessary.
