To add to this, it’s disappointing that no GOPers joined but considering none of the currently serving ones censored Gosar for essentially making a death threat against AOC then it isn't surprising. But I'm particularly disappointed in Fitzpatrick & Chris Smith, the later of whom is one of my favorite GOP reps.
Twitter is currently facilitating death threats to Republican Senators who don't fall in line with the Trump agenda. It is rather silly to expect random "moderate" Republicans to join in protests against him.
