So, pondering this; If Trump is actually under investigation, it would seem that one of the first things Mueller would have on his subpoena list, would be Trump's tax returns. Why hasn't he requested those documents? Seems that they would be easy for him to obtain. I've read that Trump has been told he isn't personally under investigation. I'm not sure if this is true, but it would seem the tax returns would have been a 1st target, if he was. Is Mueller leaving stones not yet rolled for some kind of finale'?
