President Donald Trump attended the New York Yankees' Sept. 11 anniversary game Thursday, speaking with players in the clubhouse and taking a seat in a suite protected by reinforced glass panels as law enforcement presence around Yankee Stadium was bolstered following the killing of conservative commentator Charlie Kirk.

Trump arrived in New York shortly after 6 p.m. and met with the Yankees about a half-hour before the scheduled first pitch, speaking to players and coaches in the locker room and offering words of encouragement about the team's prospects for the season. Yankees manager Aaron Boone said he was "excited" about the president's presence; several players and team officials also participated in a ceremony at Monument Park earlier in the day to lay a wreath at the 9/11 memorial.

In the clubhouse, Trump praised the Steinbrenner family and predicted postseason success for the team, at times joking with players and staff. He did not participate in the ballpark's pregame 9/11 remembrance ceremonies, but fans in the stands gave him a mix of cheers and boos before a chorus of "USA" chants later in the evening, according to pool reports. The Yankees' scoreboard earlier displayed highlights from the 2001 World Series as part of the night’s commemorations.

Security at Yankee Stadium was significantly increased for the event. The U.S. Secret Service said it had adjusted its protective posture "as needed to mitigate evolving threats" and warned attendees to expect an elevated law enforcement presence. Stadium security measures included reinforced glass panels in front of the president's suite, visible uniformed officers, and explosive-detection teams; media accounts also reported snipers posted in vantage points overlooking the field.

Teams, venue operators and law enforcement officials said gates opened earlier than usual and advised fans to use public transportation. The Yankees announced gates would open at 4 p.m., 90 minutes earlier than normal, and the club alerted patrons to the heightened screening and potential delays.

The increased protections followed the fatal shooting of Charlie Kirk at the University of Virginia on Wednesday. Kirk, a conservative commentator in his early 30s, was shot and later died, and authorities have released images of a suspect as they continue the investigation. The shooting prompted a review of protective measures at public events and heightened attention to threats against public figures and large gatherings.

The heightened security also comes while the Justice Department and federal authorities pursue a high-profile prosecution tied to an alleged attempt on Trump's life. A federal jury was seated this week in the trial of a man charged in an attempted assassination of Trump at a South Florida golf outing last year, underscoring a series of violent incidents and plots that have shaped the security calculus for the president's appearances.

Trump's visit to Yankee Stadium marked his first Major League Baseball game attendance since 2021 after leaving the White House and his first visit to a ballpark during his second presidential term. The president announced earlier this month that he would attend the 9/11 anniversary game. The Yankees had notified fans of his planned appearance on Wednesday and urged early arrival because of the expected security procedures.

Yankees manager Aaron Boone, pitcher Gerrit Cole and Carlos Rodón were among those who laid a wreath at the Monument Park 9/11 memorial prior to the game. Team officials said the organization sought to balance the night's commemorations for the Sept. 11 attacks with operational security requirements for the president's presence.

Trump has attended several sporting events over the years, including World Series games in 2019 and 2021. The Yankees and their crosstown rivals, the New York Mets, are scheduled to play at Yankee Stadium on the 25th anniversary of the Sept. 11 attacks next season. For Thursday night, club and federal authorities said they coordinated to implement additional screening and protective steps for fans, staff and players.

The president left the Bronx later in the evening and returned to Washington. Officials said they would continue to monitor threats and adjust security as needed for future appearances and national events.
