According to Chris Christie in his forthcoming book, Trump said: ‘You never know what your kids will do next.’

In his book set to be released on January 29, an advance copy of which was obtained by Jewish Insider, former New Jersey Governor Chris Christie details a conversation he had over dinner with Donald and Melania Trump in 2009 when the real-estate mogul informed him that his daughter, Ivanka Trump, had decided to convert to Judaism and marry Jared Kushner.

“It was a little hard to gauge Donald’s reaction” to Ivanka’s decision, Christie writes in his forthcoming book titled, Let Me Finish: Trump, the Kushners, Bannon, New Jersey, and the Power of In-Your-Face Politics. “He was greeting the news with what I would describe as acceptance. ‘She’s a big girl. She’s a smart girl. If that’s what she wants to do, then that’s what she wants to do. I support her. I trust her.’”

“You never know what your kids will do next,” Trump remarked, according to Christie.

But something else was also on Trump’s mind that night: his future son-in-law was the son of Charles Kushner, whom Christie, as U.S. Attorney, had sent to jail. Trump was curious to know all of the details — “including the steamy ones” — about Ivanka’s future father-in-law’s case. “There was some sleazy stuff, right? He really did that?” Trump asked the then-candidate for Governor of New Jersey. “Yes, he did,” Christie replied. ”Oh, that’s not good,” came Trump’s response.

Christie adds that Trump later called him to see whether he would consider coming to Ivanka’s wedding despite his involvement in the Charles Kushner case, an invitation which Christie politely declined. “I am confident that he was relieved that we didn’t make things awkward for him, Ivanka, and his son-in-law-to-be,” Christie writes.
