Donald Trump leads a boisterous 'U-S-A!' chant from his suite at the Steelers-Jets game.

 After a rally in Latrobe on Saturday, Donald Trump stayed in Pennsylvania to watch a primetime NFL game featuring the New York Jets against the Pittsburgh Steelers at Acrisure Stadium on Sunday night.

When Steelers fans recognized the 45th President of the United States, they erupted into a loud "U-S-A!" chant that resonated throughout the stadium.

Trump’s Deputy Director of Communications, Margo Martin, posted a video on X showing Trump pumping his fist and encouraging the Steelers fans below as they chanted. He was also seen waving to the crowd.

Former Steelers star wide receiver Antonio Brown, who spoke at the Latrobe rally and endorsed Trump ahead of this year's presidential election, welcomed the Republican candidate on the tarmac before the game.

Brown mingled with Steelers fans outside the stadium, waving yellow and black rally towels emblazoned with "Trump/Vance." He wore MAGA gear, similar to his attire at the rally the previous day.

Alongside Brown was his former Steelers teammate Le’Veon Bell, who also spoke at the rally. Both players were expected to join Trump at the game, which was attracting significant national attention.

While it was a home game for the Steelers, the Jets made headlines prior to the matchup with Aaron Rodgers reuniting with his former Green Bay Packers receiver, Davante Adams, who had been traded from the Las Vegas Raiders. Meanwhile, Steelers head coach Mike Tomlin announced a quarterback switch, with Russell Wilson making his debut for Pittsburgh.

With Trump in attendance, the Steelers implemented enhanced security measures, advising fans to arrive early for parking and entry to ensure a smooth experience. "With former President Trump expected to attend Sunday night's game as a guest of an individual suite holder, we are coordinating with the Secret Service and local authorities to guarantee the safety and security of all our fans," a statement read. "We encourage fans to arrive early to enjoy our pregame festivities and the celebrations honoring the 50th anniversary of our Super Bowl IX team."

Trump, who has a history of attending football games, was recently in Tuscaloosa, Alabama, for a Crimson Tide matchup against the Georgia Bulldogs, where he also received "U-S-A!" chants from college football fans at Bryant-Denny Stadium.
