Navy Secretary John Phelan was fired after conflicts with senior Pentagon leadership over shipbuilding, US President Donald Trump says according to Reuters.

“He’s a hard charger, and he had some conflicts with some other people, mostly as to building and buying new ships,” Trump told reporters in the Oval Office.

“Got to get along, especially in the military, got to get along, you know. And some people liked him, some people didn’t, and that’s usually the truth about everything.”
