Considerations for Possible Authorization for Use of Military Force Against the Islamic State [September 9, 2014] [open pdf - 56KB]
"The armed offensive of the Islamic State (IS, also known as ISIL or ISIS) in northern and western Iraq and northeastern Syria has raised significant concerns for the Middle Eastern governments and the United States. Since June, President Obama has ordered multiple deployments of U.S. troops to Iraq to provide security to diplomatic personnel and facilities, advise Iraqi security forces, and conduct intelligence gathering and reconnaissance. He has also ordered U.S. military airstrikes on IS forces in Iraq as part of at least four military operations since August 7. Concerned with a perceived piecemeal build-up of troops, accumulation of narrowly defined uses of force, and lack of clearly articulated strategy informed by congressional consultation and oversight, several Members of Congress have expressed the view that continued use of military force against the Islamic State requires congressional authorization. Members differ on whether such authorization should be provided."
