Trump defenders say put up or shut up, but legal experts argue that what Mueller has already established is damning and hints at shocking revelations to come.
I challenge Mueller to put up or shut up. You have no evidence of the President being involved in a conspiracy with anyone including Russia to hack. And you also have no evidence of collusion. It’s been 2 years so submit a report to DOJ and we will answer it.
