Trump’s decision to fire Rex Tillerson as secretary of state is the latest shake-up to rock the administration, which has seen an unprecedented number of top officials ousted over the last year. On Tuesday, the White House also fired the fourth-highest-ranking official in the State Department, Steve Goldstein, who served as the agency’s undersecretary of public affairs. Before he was fired, Goldstein released a statement saying Tillerson had not spoken to Trump and that he—Tillerson—didn’t know why he was fired. Goldstein was the senior vice president of BP Global Solutions before serving in the State Department. His departure leaves the State Department with only one of the six undersecretary positions filled. Tillerson’s chief of staff and deputy chief of staff also submitted their resignations after their boss was fired. Meanwhile, President Trump’s personal assistant, John McEntee, was ousted on Monday, after his security clearances were revoked following an investigation into his alleged online gambling problems and his so-called mishandling of taxes. He was reportedly escorted out of the White House so fast, he couldn’t even get his coat. But on Tuesday, only one day later, Trump’s 2020 re-election campaign announced McEntee would serve as senior adviser for campaign operations.
