Phoenix's top cop promised Monday there are sufficient protections in place for today's Trump rally to prevent a repeat of the violent clashes that happened in Charlottesville. And the reason? "We've done this before,'' said Jeri Williams. "This is not new for us.'' The police chief said Phoenix has a long history of being the site of political hot-button events, rallies and marches. And she said the police department has "great working relationships'' with many of the groups that expect to turn out both to support and hear the president as well as those who want to "exercise their First Amendment rights'' to protest.
