Postmaster General Louis DeJoy, a megadonor to former President Donald Trump, insisted during a House Oversight Committee hearing on Wednesday that he plans to remain at the head of the U.S. Postal Service "for a long time."

Richard Grenell was appointed by Trump in May of last year, and has drawn significant controversy in his relatively short tenure as ambassador. On Tuesday, Grenell openly criticized Germany’s defense spending, arguing it sent a “worrisome signal” to NATO allies. Those comments led to swift and severe backlash from several members of parliament.
