 The investigation continues for hunting for clues about what may have drove Thomas Matthew Crooks to try to assassinate former President Donald Trump. The FBI said earlier today that they were investigating it as a potential act of domestic terrorism, but the absence of a clear ideological motive by the man, shot dead by Secret Service, led conspiracy theories to flourish. The FBI says it believes Crooks, who had bombing-making materials in the car he drove to the rally, acted alone.
