In a news-making interview, former Chief prosecutor at the Southern District of New York, U.S. Attorney Preet Bharara, who was fired by President Trump in 2017, reveals to Ari Melber that he backs Mueller’s boss, Rod Rosenstein, who reportedly talked about secretly taping Pres. Trump. Bharara recounts new details about how his office also considered taping Trump when the President took the unusual step of personally calling Bharara, who concluded there was reason to have “mistrust” towards Trump. The interview is Bharara’s first day on MSNBC since he last spoke with Melber, in 2015.
