Here's what bothers me... upon what was the search of this man's home deemed necessary? As I understand it warrants for searches are granted after a judge is presented evidence/cause in response to a complaint filed by a citizen or govt. Who filed the complaint?
I don't know, but I would not be surprised to find that this man spent a bit of his money in a donation to the wrong sort of political group. Wrong from the stand point of the current admin.
My gut feeling says to follow the money trail.
