Former Chicago mayor and chief of staff to President Obama Rahm Emanuel joins "The Investigation." Emanuel, now an ABC News contributor, offers that censure in a Senate trial may be best option: "they may hit him with a yellow card...and that would be condemnation and censure." The former White House chief strategist during President Clinton's impeachment trial also makes note of the stark difference between the two president’s responses: "[Trump] is his own war room." And as more witnesses are lined up to testify in public hearings, Emanuel cautions, when asked about the significance of "star witnesses": "Don’t go chasing rabbits down rabbit holes...the king of kings here is the President of the United States."
