Republican presidential candidate Donald Trump denounced protesters in California as thugs on Friday after the latest demonstration at his political rallies turned violent in the days before the state's presidential primary. Videos posted on Twitter and online by local and national media showed clashes on Thursday evening in the street outside of the San Jose Convention Center, where demonstrators fought and threw punches. Hundreds of protesters waved Mexican flags, chanted anti-Trump slogans and burned Trump hats and at least one U.S. flag.
