The United States is doubling the number of troops on the ground in Iraq. The Pentagon said Friday it's sending up to 1,500 to help Iraqi troops who continue to struggle against ISIS with large sections of the country under militant control.
The Pentagon spokesman insisted to CNN that this latest ramp up is not mission creep.
"It's not mission creep at all," Rear Admiral John Kirby said. "Mission creep is when the mission changes or morphs into something that it didn't originally start out to be. This is very much in keeping with the missions that we have been performing in Iraq since June."
So if it's not mission creep, then what?
In June, President Barack Obama sent 300 advisers to Iraq. In September, he laid out a limited military engagement against ISIS with a pledge that it would not involve American troops fighting on the ground.
U.S. officials insist the troops are in a non combat role, but with the additional troop numbers there will be some 3,000 U.S. soldiers in Iraq - on the ground and in harm's way.
In interview with CNN's Erin Burnett, Democratic Congressman John Garamendi, who is also a member of the House Armed Services Committee says Congress was informed about the additional troop deployment.
