The planned address comes on the heels of a horrific mass shooting in San Bernardino on Dec. 2 that left 14 people dead and 21 wounded. The FBI is now pursuing the shooting, believed to have been carried out by a married couple with ties to Islamic radicals, as a terrorism attack.

In the president’s address, the White House website stated, “he will reiterate his firm conviction that ISIL will be destroyed and that the United States must draw upon our values — our unwavering commitment to justice, equality, and freedom — to prevail over terrorist groups that use violence to advance a destructive ideology.”
