Kucinich and many others believe the War Powers Resolution will require Obama to get congressional approval by this weekend, 60 days after the military mission that Obama approved without permission from Congress. He said Obama's speech appears to be an attempt to win more public support for an expanded mission in Libya.

"The President's speech tomorrow concerning U.S. policy in the Middle East is yet another attempt to stem the loss of support for our role in the war in Libya," he said. "He is up against the 60-day War Powers Act countdown from the beginning of U.S. military involvement in Libya."

Members of Congress will be closely watching Obama's remarks for signs of next steps in Libya, which could prompt an immediate discussion on whether congressional approval is needed for further military involvement.
