"Yes," Carson responded.

"There are going to be people who respond inappropriately to virtually everything," Carson added. "I think that was an inappropriate response. I don't know if, on the basis of that, you can say all Muslims are bad people. I really think that would be a stretch."

Reporters then asked Carson to clarify if he had seen the cheering on 9/11.

"I saw film of it," he said, adding that he had seen the footage in news coverage from the time of 9/11.
