From NY Post:

Twitter hosts a #KillTrump hashtag. In all of the glorious English language there is no clearer, plainer, or shorter way to call for violence than the word kill followed by someone’s name. But there it is. One of these tweets reads “#ArrestTrump not enough #KillTrump.” And this isn’t new, back in June the hashtag #AssassinateTrump was bouncing around the website with gems like “Someone take this clown out NOW.” That tweet is still up.
