 This is a special report from ABC News. Trump assassination attempt. I'm Andy Field. Former President Trump at his New Jersey home recovering from the bullet that grazed his ear at yesterday's campaign rally. Investigators looking into what prompted 20-year-old Thomas Matthew Crooks to shoot him, kill a supporter, and wound another. 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 police.
