A rift has reportedly emerged between Donald Trump’s chief strategist, Steve Bannon and his son-in-law Jared Kushner.
The pair are believed to have clashed over opposing ideological visions for Mr Trump's White House.
“[Steve] recently vented to us about Jared being a ‘globalist’ and a ‘cuck'," an official who did not wish to be named, told The Daily Beast website. "He actually said ‘cuck,’ as in “cuckservative.’”
