Supporters and opponents of President Trump clashed again at his Walk of Fame star in Hollywood, where a man was arrested Sunday night after the second big fight at the site in four days.

A man wearing a red Make America Great Again cap was shouting, “We got America great again!” and other pro-Trump slogans into a megaphone, riling up some of the president’s detractors, according to the CBS affiliate in Los Angeles.

“[This guy] came up and said he was going to pull his hat off, and . . . went up and pulled the Make America Great Again hat off and after that, everything just went crazy. They started fighting,” one woman told the station.

Another witness, Louie Martinez, said, “The kid’s father came and said, ‘Hey, that’s my son! Don’t be going after my son!’ Got up in his face, starts pushing him. Then the guy with the megaphone head-butted him,” he said.

Police wrestled the son to the ground and busted him.
