House Judiciary Committee Chairman Jerrold Nadler, D-New York, spelled out the stakes after the committee’s vote to hold Attorney General William Barr in contempt. From a Face The Nation tweet: “We are now in a constitutional crisis,” House Judiciary Chair @RepJerryNadler tells reporters after his committee voted to hold Attorney General Barr in contempt of Congress for failing to provide the full, unredacted Mueller report and underlying documents.” Indeed, if President Donald Trump can dream up a preposterous executive privilege claim to try to stop Barr from testifying and from producing the entire special counsel report, to prevent the star witness in the obstruction of justice probe (Donald McGahn, former White House counsel) and possibly to block Robert Mueller from testifying, we have no oversight process, no check on a lawless president and no accountability to the American people for the president’s actions. It’s critical to keep in mind five political and legal points. First, the basis for the Office of Legal Counsel memo has been obliterated.
