So he can ignore it when convenient like Ted “Chicago Rioter Apologist” Cruz does?
Well, let's be clear. Listen, the protesters have no right to engage in violence. They have no right to threaten violence. And these protesters, whether it's Black Lives Matter or Bernie Sanders protesters who are coming in just trying to shout down any speaker, that's not free speech. The First Amendment gives you a right to speak, but it doesn't give you a right to silence others. So the protesters are behaving abusively and wrong.
