As the U.S. military campaign in Libya approaches the 60-day mark this Friday, six Republican senators wrote President Obama asking if he will comply with the War Powers Act, which says Congress must authorize action that lasts more than 60 days. …

The GOP senators said they believe the president already violated part of the War Powers Act – which says the president’s constitutional powers allow him to only deploy troops into “hostilities” with a declaration of war, specific authorization from Congress or a national emergency caused by an attack on the U.S.

But the president did follow the provision in the 1973 law requiring him to provide information to Congress about committing U.S. forces. Now the question is whether he will abide by the part of the War Powers Act which says he must get Congressional permission within 60 days.
