Meh, so far the story says he is a white supremacist, made a so called hit list of democrats, visited white supremacist websites while at work and owned a few legal guns. Quite a few GWB, Obama and Trump haters have posted crap here about as bad. If there isn't more to what he has done, I'm calling this false news. If there is more to the story I'm listening.
In general, I do not see the point of requiring some public official to react to every crazy loser that is even remotely associated with the official. FWIW, it's the same for any party, though those that had their picture with or in any way associated with one of these crazies, e.g., Louis Farrakhan, deserve to be held accountable.
