At least two people - one being the woman who was the assistant FBI director who was fired a week or two after she met with trump and some of his staff/cabinet to warn them about General Flynn potentially being investigated for a variety of miss-deeds noted something very unusual. (I am researching who the other was)

When someone innocent is accused of something, or is told something surprising (especially if negative), they are usually very curious -‘who said that?!’, ‘who is making that accusation?!’, ‘you are kidding they did what?!’

This is generally a good indication the people you are telling this to, are innocent.

Apparently trump and his staff showed neither surprise or curiousity about Flynn, Russia. Etc.... and this was from two different people at two separate private meetings....
