Trump shooter Thomas Matthew Crooks bought 50 rounds

The Secret Service also did not sweep the roof where gunman Thomas Matthew Crooks opened fire at the former president. The horrifying new developments reported by CNN come as the Secret Service faces mounting questions over how the 20-year-old managed to get just 130 yards from where Trump was speaking in Butler, Pennsylvania on Saturday. Crooks shot Trump in the ear with an AR-style rifle his father purchased legally. A new video emerged on Monday shows Trump fans looking, pointing and questioning why Crooks was on the roof.
