Trump Thought Firing Flynn Would End ‘Russia Thing,’ Chris Christie Writes in Book

He recalled the first time he met Mr. Trump, in May 2002, at a restaurant where Mr. Trump insisted on ordering for him. When dinner ended, a fan who had waited outside for an hour asked Mr. Trump to take a photograph with her. Her camera jammed repeatedly.

Impatient, Mr. Trump looked at the woman and said, “Sweetheart, let’s do this the next time we get together.” He disappeared into a black limousine.

But Mr. Christie said there was another side to the president, describing conversations with Mr. Trump where he was concerned for his children. “What’s going to happen to them if I’m not there?” Mr. Trump wondered about his adult children if he became president.

“I think people draw him in very, very stark colors, and I don’t think that that’s who he is,” Mr. Christie said in the interview. “I think there’s a lot more nuance to it.”

Repeatedly, however, the story returns to Mr. Kushner, whom Mr. Christie recalled watching, silently, as Mr. Kushner denounced Mr. Christie to Mr. Trump in a meeting and urged him to exclude Mr. Christie from the transition effort.

“He tried to destroy my father,” Mr. Kushner said, according to Mr. Christie, a former United States attorney who prosecuted Mr. Kushner’s father, Charles, on tax evasion and other charges. Mr. Trump did not side with his son-in-law.

When Mr. Kushner lost the battle, he told Mr. Christie that they should let bygones be bygones and work together, Mr. Christie wrote. But time and again, he said, he heard from other officials that Mr. Kushner was working against him.

On election night, Mr. Kushner asked Mr. Christie’s son to take a picture of him and the governor, a moment he said he could never have imagined years earlier, according to the book. Mr. Christie was dismissed from the transition three days later.
