At least 10 people were arrested when a pro-Donald Trump rally in Berkeley, California at Martin Luther King Jr. Civic Center Park turned bloody. The violence erupted even before the event began, with people throwing smoke bombs and inciting physical fighting. Hundreds of counter-demonstrators filled the park, outnumbering the minority of Trump supporters of around 60 to 70 people. The anti-Trump protestors began to burn American flags and the "Make America Great Again” campaign hats. An elderly Trump supporter was struck in the head and kicked on the ground.
