Washington (CNN) The United States needs to provide weapons directly to the Kurdish army that is fighting ISIS in Iraq, two senators said Sunday.

Both Sen. Ted Cruz, R-Texas, and Sen. Tim Kaine, D-Virginia, told on CNN's Dana Bash on "State of the Union" on Sunday that even after a Jordanian pilot was burned alive by the terror organization, they don't want to see the United States send ground troops into the region in addition to its air strikes.

But the United States should provide more military aid to the Arab armies already fighting ISIS on the ground -- especially the Kurds' Peshmerga -- they said.

"What makes no sense whatsoever is the Obama administration is refusing to directly arm the Kurds," Cruz said. "We need to arm the Kurds now, because they are our boots on the ground."
