In a long-expected move, President Trump has fired Rex Tillerson as secretary of state and tapped CIA Director Mike Pompeo to replace him. Tillerson, one of the earliest and in the end most marginalized members of the Trump administration, has long been portrayed as the moderate voice in President Trump’s ear. Pompeo is a former Republican congressman from Kansas and a policy hawk who played a prominent role in the Congressional Benghazi investigation into Hillary Clinton. Yet far more than any policy disagreements, what sets the two apart in Trump’s Washington is their willingness to toe the president’s line in public.

Here’s what to expect from the shakeup at Foggy Bottom:

Impact

The State Department has seen better days. Pompeo takes over a State Department that is demoralized, understaffed, and consistently out of the loop regarding the Trump administration’s major diplomacy initiatives. Foggy Bottom took the brunt of cross-departmental cuts in President Trump’s first year in office, and major regional positions and ambassadorships remain unfilled, including the ambassadors to Turkey, Egypt, South Korea, and even Germany. Yet it wasn’t the health of the diplomatic corps that sealed Rex Tillerson’s fate. Rather, it was his frosty relationship with President Trump, and his evident inability to roll with the punches in Trump’s Washington. Mike Pompeo might have more luck on this score, as he has developed a close relationship with President Trump in the capacity of CIA director and hasn’t shirked from lavishing praise on the president in public statements.
