Special counsel Robert Mueller has recruited the Justice Department’s top criminal law expert to help with his investigation of ties between the Trump presidential campaign and Russian officials. Deputy solicitor general Michael Dreeben, who has argued more than 100 cases before the U.S. Supreme Court and oversees the Justice Department’s criminal appellate docket, will be assisting Mueller on a part-time basis, according to sources familiar with the arrangement. While helping Mueller, Dreeben will continue in his role in the solicitor general’s office, with other lawyers in the office pitching in to help him with upcoming criminal cases. The move signals that Mueller is seeking advice on the complexities that have arisen already in the investigations, including what constitutes obstruction of justice. "Michael Dreeben is to criminal law what Robert Mueller is to investigations,” former acting Solicitor General Neal Katyal said Thursday night. “Literally the very best. Yet another sign of how serious Mueller is about this matter." Now a partner at Hogan Lovells, Katyal has been a key figure in challenging President Donald Trump’s travel ban. In 2005, Dreeben argued and lost a case for the government involving obstruction-of-justice charges against the Arthur Andersen accounting firm in the wake of the Enron scandal. http://www.nationallawjournal.com/i...e?mcode=1202615705846&slreturn=20170509104016 Nothing to see here!
