Deputy Attorney General Rod Rosenstein has reached an agreement with Attorney General William Barr to stay on at the Justice Department “a little while longer,” according to Fox News. DOJ officials previously briefed that Rosenstein—who appointed the special counsel to investigate ties between Russia and the Trump campaign—would step down from his role in mid-March, but he’s reportedly yet to hand in his two weeks’ notice. It was thought he would quit as soon as Barr took office. Fox News reports Rosenstein would like to stay in his post until the Mueller investigation concludes, and sources confirmed to the channel that he’s still the primary liaison between department headquarters and Mueller’s office. However, Barr now has ultimate oversight over the Russia investigation. The probe is believed to be entering its final stages before its findings are handed to the DOJ.
