President Barack Obama will tell Americans on Sunday what the government is doing to keep them safe following the mass killing by a couple in California last week that is being investigated as an act of terrorism, but no major shift in strategy was expected.

In a rare Oval Office address at 8 p.m. EST (0100 GMT), Obama will lay out the security steps the United States has taken since Islamic State’s Nov. 13 assaults in Paris that killed 130 people, as well as since the Sept. 11, 2001, attacks on the United States, an administration official told Reuters.

Obama said during a recent visit by French President Francois Hollande to the White House after the Paris attacks that the United States and its coalition would step up efforts to counter Islamic State. He is likely to repeat that message from the Oval Office and, despite Republican criticism that he has not done enough to fight Islamic State, is not expected to unveil a major change in strategy.

Obama also will say he will use “every single aspect of American power” to destroy the militant group, a U.S. official said.

The official said Obama also will give an update on the investigation of U.S.-born Syed Rizwan Farook, 28, and his Pakistani wife, Tashfeen Malik, 29, in the San Bernardino, California, shooting and express confidence that the United States will prevail over terrorist threats.
