President Trump was greeted with boos and chants of “lock him up,” when he was announced at Game 5 of the World Series.

The president was seated alongside First Lady Melania Trump, several Republican lawmakers, and members of the “Wounded Warriors,” in the Washington Suite at Nationals Park. When the cameras showed the president, he was seen standing and clapping. However, when the crowd saw the president on the big screen, many began booing.

The booing continued until the screen showed members of the military, at which point the crowd began cheering again.

In addition, chants of “Lock him up” could be heard when Nationals starter Joe Ross began warming up for the fourth inning.

Nationals Owner Mark Lerner reiterated that Trump had every right to be at the game and should attend regardless of anyone’s political viewpoint.

“Well, he has every right to come,” Lerner said. “He’s the president of the United States, whether you like him or not. It’s a special event. He should be at it.”

Sunday night’s game was Trump’s first time attending a baseball game as president. He deliberately chose to arrive late, so as to not cause additional traffic problems for fans.
