President Donald Trump will be doing something that only nine other sitting presidents have done: attend the famous Army vs. Navy game in Philadelphia on Saturday. Of 119 meetings, 20 of them have been attended by a president. Trump has gone to the game before -- he attended in 2016 -- but at that point he was the president-elect and yet to be officially sworn into office. The last time a sitting president attended the game was in 2011 when President Barack Obama joined the crowd in Landover, Maryland.

Trump didn't seem to particularly enjoy what he saw a few years ago from a football standpoint, but he enjoys the atmosphere.
