 What we witnessed yesterday was nothing short of an attack on democracy and our democratic process. FBI Director Christopher Wray on the shooter killed by a Secret Service sniper, Thomas Crooks, who was 20, ABC's Aaron Katursky. They're looking for anything online that might give them a hint about motive. So far, they believe he acted alone and that there is no additional threat, but they're working to confirm that. They also have found no links to any kind of organized terror group. They're still looking.
