Nikki Haley is resigning as the U.S. ambassador to the United Nations and will leave the Trump administration at the end of the year, she said Tuesday.

It is not immediately clear what prompted the move. She informed her staff Tuesday, NPR's Michele Kelemen reports.

Shetland is an archipelago of a hundred or so islands in the North Sea, featuring ancient hills, valleys and lochs. The string of islands is known for its remote beauty: it's a 12-hour ferry ride to get there from the northeast Scottish city of Aberdeen.
