Fox News reports that “Defense Secretary Ash Carter on Wednesday endorsed the three-year expiration date in President Obama’s request to Congress to authorize military force against the Islamic State — backing off his position from just last week.”  

“The newly sworn-in Pentagon chief testified before the Senate Foreign Relations Committee, in support of the president’s new proposal for war powers to target ISIS militants.”  

“He said it gives the military the necessary authority and flexibility to wage this campaign, and specifically addressed the three-year sunset.”
