What does he feel he's going to accomplish if he gets his hands on the tax returns? Is he going to blackmail Trump out of his claim of subservience to Saudis Arabia if there's something substantial in there or will he publish them in some sort of judicial up marksmanship. The one thing I often ask myself is that if there's been years of transacting back and forth with Russia in business dealings just how is it that no one who may have been involved in those dealings have leaked anything about them? That's exactly what people expect to find but if it's in his tax paperwork then there is also other paper trails. I just don't find it logical given all the leaking going on.
