Loud boos and ‘lock him up’ chants broke out at the baseball game between Washington Nationals and Houston Astros at Nationals Park on Sunday.

The commotion happened after the US leader, who rose to his feet when a shot of US troops was broadcast during a brief intermission, was introduced to the stadium and shown on the giant videoboard.

As soon as the footage appeared, angry boos drowned out cheers for the military. Trump was apparently taken aback by the stadium’s reaction and quickly turned to his wife. It did not take him long to regain composure, however, with both Melania and him sporting bright smiles for the rest of the spectacle as if to goad those displeased by his presence.
