Presidents have sought and hired television personalities in the past. But the president's recent moves, says Michael M. Grynbaum, "are another sign that the dividing line between media and government has been all but erased under Mr. Trump, a former reality star who views himself as the casting agent in chief. Television figures have served as press aides in past administrations, tasked with handling their former colleagues in the media. But the selection of (CNBC's Larry) Kudlow crossed a threshold of sorts: the elevation of a television star to a position of real influence over policies affecting millions of Americans. It was perhaps inevitable that Mr. Trump, whose view of the world is indelibly shaped by what he sees on TV, would be a president eager to break the fourth wall."
