Trump, who converted to Judaism before marrying her husband Jared Kushner, an Orthodox Jew, in 2009, spoke about her experience in Israel, describing it as, “truly an unbelievable moment.”

“I feel blessed and privileged to have been there. It was deeply personal for me as you know to be standing at the Western Wall in a moment of privacy because it was really just us, she said.”

Trump described the trip as being “wildly successful.”

“To have covered the three largest world religions over the course of four days, it was deeply meaningful,” Trump said. “It was beyond special. For each of these moments, it’s hard to find the words to adequately describe them.”
