March 13, 2018 — President Donald Trump dumped his Secretary of State Rex Tillerson on Tuesday, according to a tweet by Trump himself. The move comes at a time when the Trump presidency is dogged by the independent investigation by Special Counsel Robert Mueller over Russian collusion in the 2016 presidential election.

Meanwhile, Gina Haspel will become the new Director of the CIA, making her the first woman to hold the position if confirmed by the Senate. She is currently serving as the Deputy Director of the CIA and has held that position since February 2017. She also has had some controversy regarding the treatment of prisoners by CIA agents.

Pompeo, a Kansas Republican, is currently the Director of the CIA, and has been serving in that position since Trump took office in January of 2017. The position as Director of the CIA was created under President Bush in 2005, and thus has had six men run the post. Before this job, he represented Kansas’s 4th Congressional District.

Trump’s reasoning behind firing Tillerson is currently unknown, though one TIME Magazine writer points to the signs of an ongoing “personality clash between the two.”
