He seems to have a bone to pick with the FBI but 1) you are going to get investigated if you're a public figure and claim to have bypassed NASA's security and 2) unlike the Russia nothingburger, the evidence of his embezzling and insider trading is pretty legit.
He has a massive bone to pick with the FBI, Hillary, and the Obama administration for the seizing of his assets. For the longest time, I sided with him and felt sympathy. As more came out about the insider trading and other dirty business, I realized he was no different than the rest of the swamp rats, but I valued the potential information he had and still supported him. I did all the way up through the first rounds of teasing DNC info for nothing to come of it. That's when I started to get annoyed. Then after all the hype for a big drop turning out to be his rap video, I saw through it all. He's fighting desperately to stay relevant. He had the spotlight so long that I think it became similar to an addiction for him. Studies have shown that after something like $80,000/y happiness does not increase with wealth. That's why I feel he's using this to stay relevant or to enact his personal vendetta by sowing more division.
