Trump shared the one thing that ruined Super Bowl LIX for him on the social media platform Truth Sunday night, Feb. 9.

WEST PALM BEACH, Fla. (AP) — As a student, Donald Trump played high school football. As a business baron, he owned a team in an upstart rival to the NFL and then sued the established league. As president, he denigrated pros who took a knee during the national anthem as part of a social justice movement.

Greeted with a mix of cheers and boos, U.S. President Donald Trump attended the Super Bowl on Sunday, the first sitting president to do so in person, despite a complicated relationship with the National Football League and a controversial history of mixing politics and sports.
