Two men, one brandishing a knife, robbed a New York City tourist of his red "Make America Great Again" hat, police said today.

The 18-year-old Danish victim, whose name was not disclosed, was about to enter the subway in Union Square Thursday at 5:40 p.m. when a man grabbed him from behind and swiped the red baseball-style cap from his head, police said.

There was a struggle over the hat when a second man flashed a knife and pointed it at the victim before the two made off with the hat, police said.
