For part of the game the president watched from the sideline, standing with cadets and also notably with General Mark Milley

Milley was nominated Saturday morning by President Trump to be the next chairmen of the Joint Chiefs of Staff potentially making him highest ranking officer in our armed forces.

The Army-Navy game is a more than century old tradition. Trump has attended before as president elect though this was his first time as president and Commander-in-Chief.
