Despite disagreements between Trump and Tillerson ranging from 45's Boy Scouts speech to the Iran nuclear deal, many were shocked at the decision to let Tillerson go.
Once called "a star" in the making by Trump, Tillerson's next concrete move following his official last day March 31 is unknown.
Before joining the Trump administration, Tillerson was CEO of ExxonMobil since 2006. With his position now filled by Darren Woods, it's anyone's guess whether the multinational oil and gas corporation will welcome the Tillerson back with open arms following his public dismissal from the White House.
