The Senate voted Thursday to open debate on a bipartisan bill that would repeal the authorizations Congress passed in 1991 and 2002 for the U.S. wars in Iraq.

Lawmakers voted 68-27 to proceed with the legislation, a move that required 60 votes and the first of several votes related to the measure.

The bill would repeal the authorizations for the use of military force for the Gulf War in 1991 under President George H.W. Bush and for the invasion of Iraq in 2003 under President George W. Bush.
