As President Barack Obama weighs U.S. options for confronting ISIS, the insurgent group in control of parts of Iraq and Syria, lawmakers in both the House and Senate are moving to ensure that the administration has the authority to take military action if necessary, Roll Call reports.  

Rep. Frank R. Wolf, R-Va., said in a statement Wednesday he will introduce legislation when Congress reconvenes next week that would authorize the use of military force against ISIS and other terror groups around the world, including al Nusra, Ansar al Sharia, al Shabaab and Boko Haram.  

Separately, Sen. John McCain, R-Ariz., said Wednesday in Virginia that Congress should not leave town in September without considering an authorization to use force against ISIS.  

Wolf’s proposal comes one day after Sen. Bill Nelson, D-Fla., announced a similar bill for the Senate as lawmakers from both chambers and both parties expressed anger and frustration over Tuesday’s release of another video showing the beheading of an American journalist by the jihadi insurgents.
