In an exclusive interview, former White House Counsel to President Obama, Kathryn Ruemmler discusses the testimony of Trump’s own White House Counsel, Don McGahn in the Mueller report. McGahn’s testimony is cited 157 times in the report and details some of the most damning episodes of Trump’s efforts to curtail the Russia probe. Ruemmler tells MSNBC Chief Legal Correspondent, Ari Melber, that “corrupt motivation” is “littered throughout” the Mueller report.
