President Trump calls for Attorney General Jeff Sessions to stop the Mueller Russia probe as the trial of former Trump campaign manager Paul Manafort gets underway. The White House calls Trump’s tweet an “opinion”. Former Federal Prosecutor Cynthia Alksene tells Ari Melber that there is “ plenty" of “obstruction evidence” and notes that Trump’s lawyer Giuliani dropped a hint in an “unhinged interview” that Trump’s team is worried Mueller now considers him a “target” rather than a “subject” of the Russia investigation.
