Tulsi is going in hard on Hillary.

Well, it's clearly just self defense of ego. They're protecting their recent endorsement of and vote for Hillary. They're got no investment in Tulsi, so it's easy to attack her.
Tulsi's play here is not for Hillary voters anyway. She might make an interesting VP pick to snipe some wobbly Trump voters.
Those who label words as violence do so with the sole purpose of justifying violence against words.
