Several videos online show the incident from different angles.
Some people in the socially distanced stadium could be heard booing, flipping the middle finger, and what appears to be a bodycam video from the people involved.
Naturally, social media users were quick to comment on the matter. Check out what they had to say.

Although residents of Trump's hometown in New York seemed to dislike him, this isn't the first time that a supportive banner has been spotted at a ball game.
During a Yankees versus Kansas City Royals game in July 2018, Trump supporters hung a "Trump 2020" banner, which was met with boos and cheers.
In May 2018, Rudy Giuliani— the former New York City Mayor and Trump lawyer—was met with countless boos at Yankee Stadium's Memorial Day game when his 74th birthday was announced to people at the game.
In Thursday's games, the Toronto Blue Jays won the first game 2-0, and the Yankees won the second game 5-3.
