Key Evidence
The Independent and Hindustan Times both report loud booing when Trump appeared on the jumbotron during the national anthem.

Multiple sources note a 30-minute delay due to security concerns related to Trump's arrival, indicating a significant disruption linked to his presence.
What the Evidence Shows
Multiple independent and reliable sources confirm that Donald Trump faced loud booing from the crowd during his attendance at the 2025 US Open men's final. The booing occurred notably when he appeared on the giant screen (jumbotron) and during the national anthem, as reported by The Independent, Hindustan Times, Rolling Stone, and others. The booing was significant enough to be audible on national broadcasts despite efforts by the United States Tennis Association (USTA) to minimize or censor crowd reactions.
Additionally, Trump's presence caused heightened security measures and a delay in the match start time by approximately 30 minutes. Some sources also note that while there were boos, there were mixed reactions including some cheers, but the dominant reaction reported was booing. Videos and eyewitness accounts corroborate these reports.
The crowd's reaction was strong enough to be widely covered in both sports and political media outlets.
