They know that once anyone gets their hands on these records, they will be immediately leaked to the media/dem complex, and the leaker(s) will not be punished but instead praised.
President Trump should never turn over his records to anyone, without indictment. Otherwise, show cause. This ruling will effect Presidential nominees for years to come and have a devastating ramifications forever. First class nominees will never run for office. All we will have to vote for are Schiffs, Ryans, and Romneys to name a few. An indictment must be if order to force a President to release Tax Docs. If President Trump is forced to release the docs, he should resign in contempt.
