In an interview Sunday on CBS' "Face the Nation," Kelly said he supported an assault weapon ban, but that in New York City, "the problem is the handgun."
He said 60 percent of murders in the city are done by handguns.
Kelly was in support of universal background checks. He said about 6 million weapons were sold last year without one.
