 Fox has learned that the Trump Secret Service protection had been bolstered in recent weeks after U.S. intelligence that there was an Iranian plot to assassinate the former president. Now, there's no connection between that and the 20-year-old gunman in Pennsylvania, Thomas Matthew Crooks. Investigators are still trying to figure out his motive in the shooting that also left a Trump rally attendee dead. Cory Comperatore was killed shielding his family from the bullets.
