The biggest thing of note that I could find for that date is this. (pic related)
But you can look at this list and see if you find what you are looking for.

Alan has been on Fox three times this week (that I have seen) Including tonight on Sean Hannity. All three times he has said "I am not working for the President"
There has to be a reason he keeps stressing that. He makes it very clear he is only speaking on TV but not giving the President advice. He says "But if I were going to advise a client…"
Either he isn't actually working for Trump, perhaps because he is going to be a witness, or they don't want to make it public.
