President Barack Obama stunned nearly everyone, including some of his own advisers, when he announced he would seek congressional authorization before ordering military strikes on Syria. The Senate Foreign Relations Committee opens hearings this afternoon, and the House and Senate promise up-or-down votes by next week. Obama’s decision puts his critics in Congress on the spot about what to do in response to Syria’s alleged use of deadly sarin gas against civilians. But he also has reversed the course charted by other modern presidents, including his own decision two years ago to strike Libya without asking Congress first. A panel joins guest host Susan Page to discuss the battle ahead in congress, the reaction from around the world, the impact on this week’s global summit in St. Petersburg, Russia, and the repercussions that could follow for this president and future ones.
