President Donald Trump’s choice to be the top U.S. military officer, retired Air Force Lt. Gen. Dan Caine, endeared himself to the commander in chief through his military call sign, “Razin,” during a meeting in Iraq years ago. Officials who have served with Caine described him Saturday as measured and apolitical. Trump said Friday night that Caine was his pick as the next Joint Chiefs of Staff chairman, making the announcement in the same social media post in which he fired Air Force Gen. CQ Brown Jr., who had held that job for 16 months after a career as a history-making fighter pilot.
