USA 🇺🇸: The U.S. Secret Service reported that local authorities were alerted to a threat before Trump's rally but failed to find the shooter in time.

Local police were alerted to a suspicious individual by attendees, but they could not locate him before he climbed onto the roof and opened fire, according to U.S. Secret Service spokesman Anthony Guglielmi.

Mr. Guglielmi told Fox News that the first time Secret Service agents saw the shooter, he was already on the roof, shooting. At that moment, "a Secret Service sniper neutralized him," Guglielmi said, as reported by Fox News.
