I am sure you know trump has his own personal photographer who follows him everywhere .( looks to be about a 25 year old female). Apart from making the bad choice to use Canon ( spits here) if you look closely you will see the hammer head flash is mounted horizontally very close to the top of the camera and right over the lens. Looks like she has learned that provided she shoots landscape she will got no side shadows. This replicates my use of the SB400 on a flash flipper. Although she clearly has a bracket to hold the unit I could not tell if it rotated for portrait shots. Seems to be a simple L bracket with a flash shoe mounted vertically rather than horizontally.
