Why wouldn't he? What is he hiding, and has been hiding since he was asked to do so 2 years ago? Every candidate and every President in modern history has done so - except 45. What we do know is that the last time he was bailed out of bankruptcy (5th or 6th time?), it was Russian Money that did so.  I am incredulous that supporters of 45 would tolerate such a lack of transparency. Aren't you curious???
