According to Wolff, Treasury Secretary Steven Mnuchin and Reince Priebus, the former chief of staff, called Trump an “idiot.” (So did the media mogul Rupert Murdoch, owner of Fox News, though he used an obscenity first.) Trump’s chief economic adviser, Gary Cohn, compares his boss’s intelligence to excrement. The national security adviser, H. R. McMaster, thinks he’s a “dope.” It has already been reported that Secretary of State Rex Tillerson called Trump a “moron,” which he has pointedly refused to deny.
