“He's like a bull seeing red,” this person added. “There's just no getting through to him, and you can kiss your plans for the day goodbye because you're basically stuck looking after a 4-year-old now.”
“No one knows what to expect from him anymore,” one former White House official, who spoke on the condition of anonymity to discuss internal conversations about the president, told Insider. “His mood changes from one minute to the next based on some headline or tweet, and the next thing you know his entire schedule gets tossed out the window because he's losing his s—.”

When he did travel abroad, to the G7 in Biarritz, he made so many outlandish claims that even those leaders who thought they had figured out how to put up with him were reduced to stunned silence.
