Via The Hill:

President Obama will seek to convince Sens. John McCain (R-Ariz.) and Lindsey Graham (R-S.C.) to support limited military strikes against Syria during a White House meeting on Monday.

McCain and Graham will meet with Obama at about 2 p.m.

McCain and Graham support military action, but argue the strike under consideration by Obama is too limited, and their support of congressional authorization is in doubt.

If Obama can bring the two around, it would greatly increase the chances of military authorization being approved by the Senate, though winning House approval could remain difficult.
