 He was using, we believe, an AR-15 semi-automatic rifle, and authorities are checking out his house now. JJ, there's a question that's being raised here because several people say they saw this man on the roof of this building close in the proximity to Donald Trump, 200 yards, the length of two football fields. Is there a disconnect here between the Secret Service, what they're doing, and what the local police and the Sheriff's Department are doing?
