President Obama to Deliver Rare Oval Office Speech on San Bernardino Shootings

— -- President Obama will address the nation Sunday evening on the San Bernardino shootings in a rare speech from the Oval Office.

The White House announced the speech as a new addition to the president's weekend schedule, with it scheduled for 8 p.m. ET Sunday.

It will be Obama's third Oval Office speech as president, his first since announcing the end of U.S. combat operations in Iraq on Aug. 31, 2010.

Obama met with his national security team to receive an update Saturday morning on the San Bernardino shooting, reaffirming the FBI had not yet found any indication the two shooters were part of any larger international terror networks or cells.

According to the White House, the president is also expected to discuss "the broader threat of terrorism, including the nature of the threat, how it has evolved, and how we will defeat it."
