A mystery case that is reportedly connected to the Mueller probe makes its way to the Supreme Court, as President Trump’s lawyer, Rudy Giuliani, claims Trump will not be “answering any more questions” from Mueller’s team and with no evidence, alleges Mueller mishandled evidence. Former U.S. Acting Solicitor General under President Clinton, Walter Dellinger, tells Ari Melber he “would expect” Mueller to “seek to subpoena” Trump before concluding his investigation.
