Trump officials believed to be WHCD gunman's target, acting AG says

Driving the news: Officials believe the suspect took trains from California to Chicago and then to Washington, where he checked into the hotel where much of the nation's power structure would soon gather.

• Blanche said on ABC's "This Week" it appears the gunman checked into the hotel on Friday. His motive remains under investigation.
• The suspect, who is expected to be formally charged Monday, is not cooperating, Blanche told CBS News' "Face the Nation." He is expected to be charged with two counts: assaulting a federal officer and use of a firearm during a crime of violence.
• He was armed with a shotgun, a handgun and multiple knives, interim Metropolitan Police Chief Jeffery Carroll said in a news conference with D.C. officials.

What they're saying: "The system worked," Blanche said of the security that foiled the gunman, the tone a sharp contrast from the fallout from the security failures surrounding the Butler, Pennsylvania, attempt on the president's life.

• "Law enforcement and the Secret Service protected all of us," he said. "The man barely got past the perimeter."
