Meanwhile, the Senate Foreign Relations Committee is starting markup on its draft Syria attack resolution. Committee members will be working from a draft resolution authored by the Senators Robert Mendendez and Bob Corker, the committee's chairman and ranking member.
The draft resolution gives President Obama authority to attack Syria to "degrade" Syria's chemical weapons arsenal and to deter it from future attacks. It creates a window of 60 days for the president to act, though that could be extended to 30 days, and it would prohibit the use of ground troops in carrying out its objectives. Senator John McCain has already signaled his opposition to the resolution.
You can watch the proceedings on C-SPAN2 or online at c-span.org. The markup was scheduled to begin at 11:30 AM ET.
