Robert S. Mueller, named special counsel to investigate potential coordination between Russia and the Trump team during the 2016 presidential election, became the sixth director of the FBI in 2001. He spent much of his 12-year tenure wrestling the agency into a battle-hardened terrorism-fighting force after the Sept. 11 attacks.
