Donald Trump is reportedly already turning on Mick Mulvaney—who hasn’t even started his new job as acting White House chief of staff yet—due to a two-year-old video uncovered by The Daily Beast, which shows Mulvaney calling the president “a terrible human being.” Mulvaney is due to start his new job at the end of the year. Trump’s announcement of Mulvaney’s appointment followed a troubled hiring process that saw several of his preferred picks refuse the role. Trump reportedly started regretting his appointment after seeing the video of Mulvaney from a week before the 2016 election saying: “Yes, I am supporting Donald Trump, but I’m doing so despite the fact that I think he’s a terrible human being.” Axios reports Trump was “furious” when he heard about the footage—he reportedly asked one adviser: “Did you know [Mulvaney] called me ‘a terrible human being’ back during the campaign?” A spokeswoman for Mulvaney dismissed the remarks as “old news” and said he changed his mind about Trump after they met.
