Sen. John McCain (left), R-Ariz., accompanied by Sen. Lindsey Graham, R-S.C., speaks with reporters Monday outside the White House in Washington following a closed-door meeting with President Barack Obama to discuss the situation with Syria. President Barack Obama, working to persuade skeptical lawmakers to endorse a U.S. military intervention in civil war-wracked Syria, hosted the two leading Capitol Hill foreign policy hawks for talks and directed his national security team to testify before Congress in a determined effort to sell his plan for limited missile strikes against Syrian President Bashar Assad's regime.
