Former Exxon head Rex Tillerson is officially the new U.S. secretary of state.
The vote was unusually close for the position — Tillerson's predecessors easily cleared the 60-vote supermajority threshold.
That's probably because Senate Democrats have faced increasing pressure from their base to reject all of President Donald Trump's nominees.
Tillerson takes the helm at a difficult time for the State Department. Several top-level departures have left holes in the department's leadership structure.
And more exits might be coming. Over 900 State Department diplomats signed a memo objecting to Trump's immigration ban. White House press secretary Sean Spicer recently suggested that any official who isn't on board with Trump's actions might have to leave their post.
