Sen. Mitch McConnell (R-Ky.) on Tuesday announced his opposition to the Senate resolution that would authorize the use of force in Syria.

McConnell becomes the only top party leader in Congress to oppose the use of military force, as Senate Majority Leader Harry Reid (D-Nev.), House Speaker John Boehner (R-Ohio) and House Minority Leader Nancy Pelosi (D-Calif.) are all in favor.
