"Neighbor: Trump Sign in Yard Belonged to Thomas Matthew Crooks"

Thomas Matthew Crooks, a 20-year-old gunman, fired shots at Donald Trump during a rally in Butler, Pennsylvania, killing one person and injuring two others before being shot dead by Secret Service. Despite having pro-Trump signs in his yard, Crooks' political motives remain unclear. The FBI is investigating the incident as a potential act of domestic terrorism. President Joe Biden has urged the public not to make assumptions about the shooter's motives.
