John Feeley, the United States' ambassador to Panama, has resigned, stating that President Trump's policies make it impossible for him to work in an apolitical fashion, per Reuters. His resignation came yesterday, according to Univision, before Trump's widely reported comments branding African nations as "shithole countries."

From his resignation letter: "As a junior foreign service officer, I signed an oath to serve faithfully the president and his administration in an apolitical fashion, even when I might not agree with certain policies. My instructors made clear that if I believed I could not do that, I would be honor bound to resign. That time has come."
