No info on the GI?
They like to remain anonymous. Ollie North used to be one of the unidentified GIs in White House photos until events changed things.
He is likely the President’s Air Force Aide. Each service provides two officers as Aides to the President and VP. If you go back to the photo of Obama’s team at the Bin Laden raid, an Air Force Officer is working the computer keyboard while Obama sits in the corner. Not so here.
