The art of the evidence-free claim. How Trump gets by without sourcing what he says

“A big element of his communication style is storytelling. Americans that listen to the president aren’t looking for precision on the facts. They’re looking for the macro wave of the story,” said Scaramucci, who has kept in touch with Trump since being fired from his White House job last July.

“He’s going to get some things wrong about the facts of the situation, but his gut instinct is right. That’s why he speaks in those broad overtones,” Scaramucci said.

Historians and veterans of past administrations acknowledged the strategy is effective, even as they lamented how it was reshaping the presidency.

In the past, “being caught in a lie, or caught in a serious misstatement that was not checked in any way, was very, very politically dangerous for a president,” said Philip Heymann, a former senior official in the Justice Department under Presidents Jimmy Carter and Bill Clinton.

“Trump has a base that isn’t much affected by whether he lies,” said Heymann, who served on the Watergate prosecution team. “He can say things that are false if they represent views that his base wants to see espoused. It’s a totally different game.”
