Pompeo was himself a former congressman. He aspired to run for the Senate. He yearned for the approval of Trump, who never got along with his predecessor Rex Tillerson. Tillerson angered his boss, once reportedly calling him a “moron.” Pompeo would not make that mistake. He spent his tenure trying to do everything he could to please Trump, even if it meant turning the State Department into an arm of the president’s reelection campaign. The damage he did to American foreign policy in the process is immeasurable.
