U.S. Secretary of State John Kerry and Defense Secretary Chuck Hagel on Wednesday testified in a House of Representatives hearing about Syria, striving to sell President Barack Obama's plan for a punitive strike against the government of Bashar al-Assad for alleged use of chemical weapons. Kerry, echoing Obama, said the "red line" against the use of chemical weapons wasn't drawn by the president alone, but "this is about the world's red line," while promising the House Foreign Relations Committee that there would be no boots on the ground in a strike against Syria.
