The president wants to use U.S. military airstrikes in Syria to defeat the Islamic State, also known as ISIS and ISIL, and does not believe he needs authorization, a source told the Washington Post. When Obama met with congressional leaders from both parties, he reportedly made it clear he believed he has the right to attack the militant group to protect U.S national security, sources told the news site.

The president will ask Congress on Thursday to “quickly authorize” training and arming Syrian opposition forces, the Associated Press added. Obama will reportedly present a broad strategy that might include wide-ranging airstrikes. He allegedly said he would welcome action from Congress that would "aid the overall effort and demonstrate to the world that the United States is united in defeating the threat," the AP wrote.

Obama "will pursue a comprehensive strategy to degrade and ultimately destroy ISIL, including U.S. military action and support for the forces combating ISIL on the ground — both the opposition in Syria and a new, inclusive Iraqi government," said a statement from the White House, according to USA Today.

U.S. Secretary of State Kerry told reporters that Obama would provide "a more detailed description of exactly what the United States is prepared to do together with many other countries in the broad coalition in order to take on this terrorist structure, which is unacceptable by any standard anywhere in the world."
