Correction: A previous version of this post misspelled the White House chief of staff's first name. It is Denis. 

The looming congressional debate over whether to intervene militarily in Syria dominated the discussion on the Sunday morning political talk shows.

White House Chief of Staff Denis McDonough made the rounds arguing on each of the major shows that Syria's alleged use of chemical weapons on its own citizens necessitates a U.S. military response. He said it was "too early" to count votes when asked about Washington Post reports that a majority of the House is committed to or leaning toward voting against authorizing force. Republicans tried to attach military funding to the debate and Charlie Rose previewed a Sunday morning interview with Syria's President Bashar al-Assad, to air on PBS on Monday night.

The president will continue his full-court press on courting support for a military strike, with plans to sit down for Monday interviews with PBS, CNN, ABC, CBS, NBC and Fox News Channel. On Tuesday, he will make his case to the nation. Administration officials estimated Saturday they had already contacted 85 senators and more than 165 House members.
