Found the footage, raw footage from CSPAN of Trump walking over to the church with his bible. Milley behind him and you catch sight of his fatigues that he stays behind the press taking the pictures. I think Trump was definitely making a point about prayer and faith and when he asks people to join him Milley is not with the rest of the group. Bad optics for him maybe.
