President Trump has placed Kushner at the center of his efforts to secure a Middle East peace deal.
At an event for donors and Republican supporters the night before the inauguration, Trump addressed Kushner in his remarks and said, "If you can't produce peace in the Middle East, nobody can."
Israeli Prime Minister Benjamin Netanyahu also highlighted his longstanding ties to Kushner in a show of support for Trump when he visited the White House in February.
"Can I reveal, Jared, how long we’ve known you?" Netanyahu said while addressing Kushner, who was seated in the front row of the crowd.
"Well, he was never small. He was always big. He was always tall," Netanyahu said, alluding to Kushner's height, even as a young child.
