Under the War Powers Act, the president can commit U.S. troops without congressional approval, but only for 60 days. Some members believe the Obama administration violated the act because the 60-day period expired last week and Obama sought no approval from Congress.

Others, such as Rep. Dennis Kucinich (D-Ohio), believe the War Powers Act was never an appropriate justification for the military operation in Libya in the first place because it only allows troops to be committed by the president in cases of immediate threat to the United States.
