A White House Press Release announced that on Wednesday, February 11, 2015, “President Obama transmitted to Congress a proposed authorization for the use of military force, or AUMF, against the Islamic State of Iraq and the Levant, also known as ISIL.
ISIL poses a threat to U.S. national security, which is why U.S. armed forces are already working with some 60 other nations and partners to degrade and ultimately destroy ISIL. The President has said that we are strongest as a nation when the President and Congress work together, and enacting a bipartisan AUMF against ISIL would provide a clear and powerful signal that the United States stands united behind the efforts to degrade and ultimately destroy ISIL.”
