Pretty good theory on twatter…guy does a good job.
Theory is that Trump has worked with FBI for years..helping to get info on Russian operatives in the casino and construction biz. He was the 'Atlantic City casino owner' listed in FBI docs.
Theory says that when Trump got the nomination, the 'sting' Trump had been helping with (including Sater) was then used against him as the 'collusion case'.
Not sure, but does seem plausible, considering Trump's interviews and speeches over the years.
