My thoughts, too.
I’d have General Kelly do it. When he complains, “hey what are you doing”, Kelly can say, “Really? You were quoted as wanting to wear a wire around the President. We have to be careful.” Make him feel like the two-bit rat that he is.
Also, take his phone. Omarosa used hers to record convos, some with Kelly. Can’t be too careful.
don’t forget to pat him down for a shoe bomb or underwear bomb before wheels up
