 BBC News with Chris Barrow. Donald Trump has told a Republican campaign rally that he's not a threat to democracy, saying he took a bullet for democracy, a reference to the failed assassination attempt against him last Saturday. Officials investigating the attack on Mr Trump say they believe the gunman flew a drone over the rally site to scope it out ahead of the shooting. They said they found a drone in Thomas Crook's car after he'd been shot dead by the Secret Service.
