The White House announced that President Barack Obama will be speaking about Syria at a briefing that was scheduled to be held at 1:15 p.m. ET Saturday.
Obama said on Friday that he has not made a final decision on a response to Syria's chemical weapons use.
Obama said "this kind of offense is a challenge to the world" and that chemical weapons use in Syria threatens U.S. national security interests as well as U.S. allies such as Israel and Jordan.
While Obama hasn't decided on a response, he said he is looking at limited action, not an open-ended commitment.
Republican Senators John McCain of Arizona and Lindsey Graham of South Carolina said in a statement the Obama administration should "delay no further in taking military action." They said that the goal of any action should not be to help the President save face, but to "shift the balance of power on the battlefield against Assad and his forces."
Obama's remarks follow a statement by Secretary of State John Kerry laying out the case for action against Syria.
