The word “assignation” rather that murder has always left me wondering why it’s assignation on a leader and murder for the common folk. But yeah, calling for the murder/assignation of Trump has gone beyond the pale for this ignoramus. He thinks he’s okay under protected speech but calling for the killing of someone???
They used the word "assault", which doesn't mean "killing" or "murder". Assasination is killing. "Assignation", which you are using, is a secret meeting, or tryst (if you are meeting your lover).
The article's writer is using "assault" when it is plain that Beck and Thor are talking about killing Trump --- as a "patriotic act". That would be assasination.
