Deputy Attorney General Rod Rosenstein is expected to leave his position as soon as the new attorney general is confirmed, according to emerging reports. Last month, Trump nominated the former attorney general for George H.W. Bush, William Barr, for the position. Barr is known for his expansive view of executive power and had previously sent an “unsolicited memo” to Rod Rosenstein criticizing special counsel Robert Mueller’s ongoing Russia investigation. Rosenstein was seen by many as helping to protect Mueller from being fired and from other White House interference. If confirmed by the Senate, Barr will oversee Mueller’s probe. In November, Trump retweeted an image from a pro-Trump Twitter account featuring Rosenstein as well as Robert Mueller and a range of prominent Democrats, including the Clintons and Barack Obama, behind prison bars. Text overlaid on the image reads: “Now that Russian collusion is a proven lie, when do the trials for treason begin?”
