I think it is valid to think he went to his Virginia Golf course. I know it was too late and too wet for a round yesterday. It does all appear rather odd that he was wearing golf shoes on the plane. I don't know if he was even in MAL yesterday. I don't believe it is a medical issue, TBH. If I'm proven wrong, I can live with it, but this was an interesting thing from a random person on the Twitter:
In this video you can see that he was still in golf clothes and shoes. So was the female SS agent. They got into vehicles with USG license plates, not typical SS vehicles they use when he is in protective care.
