Agreeing to testify and 'reveal' whether or not there are tapes means jack shit when you're dealing with a known liar. So good on Scrotus for 'agreeing' to testify, but I won't believe a word he has to say. If, that is, he says anything other than "I claim Executive Privilege" or "In the interests of National Security".
I think he and Melania went to Camp David to measure it for golden toilets, royal purple velvet draperies, and Louis Quatorze white-and-gilt furniture. Bring on the bling!!!!!
