MSNBC national security analyst Clint Watts said Wednesday on “Katy Tur Reports” that former President Donald Trump was a “galvanizing force” for a lot of extremist groups which are now domestic terror threats. Tur said, “The Justice Department is creating a unit to fight domestic terror. The threat of home-grown extremism has grown over the last year with the number of FBI investigations into domestic terror more than doubling since the spring of 2020.”
