Former US president Donald Trump kicked out a protester during his rally in Manchester on Saturday night. It was about an hour into his campaign event at the SNHU Arena in Manchester when a man in the crowd shouted, “He’s a dictator.”

“Get him out,” Trump said, and security immediately surrounded the man, according to the Daily Mail. He was then removed from the arena.

“Now we know that politics is getting serious,” Trump said.

The former President slammed Nikki Haley for earlier questioning whether he was mentally fit enough to be president. “I feel my mind is stronger now than it was 25 years ago. Is that possible?” he said.
