On Tuesday's edition of MSNBC's 'Morning Joe,' Sen. Bob Corker discussed the dangerous situation in Syria. EUGENE ROBINSON, "THE WASHINGTON POST": Senator, the other day we saw U.S. forces shoot down a Syrian warplane. We've heard the Russians threaten to shoot down U.S. warplanes. What does all this mean in terms of our involvement in Syria and the relationship with Russia? CORKER: Great question, Gene. We're today, you know, taking out the AUMF again and we're beginning hearings. It's my goal to actually take action on this at some point. We want to make sure we do it in the appropriate way. But we're right on the fringes, aren't we, where, in essence, we have U.S. troops there that are helping facilitate the SDC go into Raqqa and we've got the Syrian forces, who are infringing upon that. And we took them out as we should. And so we're right on the edge of that, aren't we, where we actually have a brewing conflict that could spill over into actions between us and the Syrian regime. That definitely is not authorized. And, again, it's my hope that this is going to simmer — or cool down and not lead to any further conflict. But, look, I support what the U.S. has done to protect the SDC, which is going in against Raqqa, people that we have armed, people that we have helped train. And, yet, we're in a place that, again, I hope will cool down before it gets into further complications.
