Sen. Ted Cruz, a potential presidential candidate is 2016, isn't ruling out sending American ground troops to fight Islamic State militants.
The Texas Republican tells ABC's "This Week" that "if need be, we should go that step. But it should be driven by the mission."
Cruz, who was attending an international security conference in Munich, wants to use Kurdish fighters — known as the peshmerga — as the ground forces in combination with U.S.-led airstrikes. He says those fighters are effective and ready.
"We need to arm the Kurds now because they are our boots on the ground," he told CNN's "State of the Union."
