President Donald Trump is expected at Saturday’s Army-Navy Game in Philadelphia.

The game, at Lincoln Financial Field, will be the third college football game Trump’s attended since his election in November 2016. He was at Army-Navy in Baltimore while president-elect and remarked on CBS that it wasn’t “necessarily the best football.” He later showed up at the Alabama-Georgia Playoff National Championship in January 2018.

This trip adds to a long history of presidential visits to college games, which dates at least back to Theodore Roosevelt and includes Richard Nixon’s declaration that 1969 Texas-Arkansas should function as the national title game.

The vast majority of presidential games are Army-Navy, which has at least one high-level executive branch member in attendance every year. That might be the president, the vice president, or the secretary of state or defense.

This unofficial list includes games attended as president-elect. It’s adapted and updated from an earlier version by historian C.J. Schnexnayder at Football Study Hall.
