Sen.
Bernie Sanders condemned any of his supporters making “vicious personal attacks” against others.
According to Politico, Nevada’s Culinary Union offered criticism over his Medicare for All proposal.
Afterwards, two top union officials received threatening messages over the phone, email and Twitter from Sanders’ supporters.
The union then announced it would not endorse any political candidate ahead of the Nevada caucuses.
Sanders said: “I don’t tolerate ugly attacks against anybody.”
