Special Counsel Robert Mueller is already closely managing the Russian election meddling investigation he was appointed to oversee, receiving daily briefings and weighing in on investigative tactics, a spokesman told NBC News.
Mueller was appointed May 17 after the deputy attorney general, Rod Rosenstein, took himself out of overseeing the Russia investigation.
Members of Congress called for a special counsel after President Donald Trump fired FBI Director James Comey, a decision that Rosenstein fully supported.
