Chairman of the Joint Chiefs of Staff: Troops could be redeployed in Iraq

Chairman of the Joint Chiefs of Staff, General Joseph Dunford, says he would consider recommending putting U.S. forces with Iraqi troops to fight Islamic State if that would improve the chances of defeating the militants.

"If it had an operational or strategic impact and we could reinforce success, that would be the basic framework within which I'd make a recommendation for additional forces to be co-located with Iraqi units," Dunford told a Senate hearing.
