President Donald Trump returned to his hometown of New York City on Thursday to participate in ceremonies commemorating the 24th anniversary of the September 11, 2001 attack on the World Trade Center. This also included a visit to Yankee stadium to watch the New York Yankees play against the Detroit Tigers.

The crowd responded to Trump on two different occasions. As he was being seated in a VIP box (surrounded by bulletproof glass), fans can be heard both booing and cheering as the president while he made his initial entrance.

"Quite a few Bronx cheers and boos, as President Trump arrives to his box at Yankee Stadium," Washington Post White House bureau chief Matt Viser tweeted.

However, Trump's presence also appeared to prompt a reaction from the stadium's sound engineer. During the second inning, Yankee Stadium's announcer can be heard introducing Trump to the crowd as the "45th and 47th president of the United States on the solemn anniversary of September 11, 2001." At that point, a loud whistle is heard echoing throughout the stadium.

That sound effect is known as the "P.C. Richard Whistle," which is typically played after a batter on the visiting team strikes out. It can also be heard in several other videos showing Trump at Yankee Stadium.

"Donald Trump introduced to the crowd at Yankee Stadium in the middle of the second inning and whoever is in charge of sound effects played the PC Richard whistle, which is what is traditionally played after a strikeout," one X user posted. "This person should and will be fired."
