It's nice for unconditional Trump supporters who are defining "an adult" as being someone who is willing to serve as the President's personal defense attorney, even though that is not a part of the official capacity of their office. That is, an Attorney General who is willing to obstruct investigations of the President and his associates, use the power of their office to thwart active prosecutions of the President and his associates, undermine resolved criminal cases, seek vindictive prosecutions of the President's political enemies and also perform public relations work for the President on Fox News.
... and then we have this:
1) Per The Hill from yesterday morning, according to Attorney General William Barr, President Donald Trump officially fired Southern District of New York Prosecutor, Geoffrey Berman, on Friday night. Berman had led multiple investigations into Trump associates, including Michael Cohen and Rudy Giuliani.
2) Per CNN from yesterday afternoon, President Donald Trump said, "I'm not involved," when he was asked about the firing of Southern District of New York Prosecutor, Geoffrey Berman.
Also, in a surprise move of integrity, Sen. Lindsey Graham has said that he won't take up the U.S. Attorney pick to replace Berman without both Senators from New York, Democrats Chuck Schumer and Kirsten Gillibrand signing off on the permanent replacement. So, Barr may think he has accomplished something greater than what will prove to be the reality here.
