In a special report, MSNBC Chief Legal Correspondent Ari Melber examines the tactics of a hardball Federal Prosecutor on Special Counsel Mueller’s team, Andrew Weissmann, who many refer to as Mueller’s “legal pit bull”. Melber breaks down how Weissmann honed his hardball strategy in the Enron investigation, one of the most far-reaching, aggressive and controversial prosecutions in modern American law and how he built a reputation of effective and controversial prosecution, by charging targets that many prosecutors avoid: like a defendant’s own family members.
