56 year old John Feely, career diplomat and former Marine chopper pilot, serving as America's ambassador to Panama has resigned his post.
"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," he wrote, in a letter obtained by Reuters.
"My instructors made clear that if I believed I could not do that, I would be honor bound to resign. That time has come."
He was nominated to the ambassadorship by President Barack Obama in July 2015 and was sworn in to the post on January 15, 2016.
Before becoming ambassador to Panama, Mr Feeley served as principal deputy assistant secretary for Western Hemisphere affairs from 2012 to 2015.
The ambassador is just one of many veteran diplomats and foreign service staffers who have voted with their feet, hollowing out the State Department, since Deplorable Donnie took power. With them goes a lot of institutional memory - the people who knew how things worked, who knew the people to call in other countries' foreign service when a favour was needed or a deal had to be negotiated. These were people other countries had come to trust.
