Trump says John Kelly will be leaving at the end of the year https://www.foxnews.com/politics/trump-says-john-kelly-to-leave POTUS keeps repeating that Kelley will be leaving at the end of the year... 4-5x.  Did not say Kelley was retiring, but leaving.  End of the year is the day before the new UCMJ rules go into effect.  Someone elsewhere speculated that maybe Kelley was going to oversee military tribunals.  Not that far fetched.
