Obama phones bipartisan group of senators to rally Syria support

The president has been aggressive in courting members of Congress, meeting with Sens. John McCain (R-Ariz.) and Lindsey Graham (R-S.C.) on Labor Day at the White House. On Tuesday, Obama hosted congressional leaders and the chairmen of the Intelligence, Foreign Affairs and Defense committees at the White House before departing for Sweden ahead of the G-20.

Meanwhile, administration officials have fanned out to brief members of Congress on Capitol Hill, including estifying in a series of classified briefings.

Earlier Thursday, Rhodes wouldn't rule out the possibility, floated earlier in the week by Secretary of State John Kerry, that Obama might address either the American people or Congress about the situation.

"We don’t have a particular speech planned at this point, but we certainly do think that the President will be out there making the case to Congress and the American people," Rhodes said. 

"He’ll have multiple opportunities to do so. Yesterday and today and tomorrow, he’ll be able to make that case on the world stage and I think it’s important for the world to hear the view of the United States on this issue, particularly because our view is rooted in an international norm that has the support of the international community that we believe must be enforced."
