Why wouldn't Trump simply enter the church and say some prayers and come out and say that he prayed for the nation and he prayed for peace and he prayed for George Floyd and his family?
It'd be so easy, just answer the press questions about why he came and what he did.
No one in the WH could think of that?
It'd give a purpose to the visit, send a unifying/calming message, and avoid the awkward bible holding photo op, which was way too obviously just a political photo op.
