That spring, just a few months later, Mr. Kushner successfully urged his father-in-law to make his first international trip to a summit in Riyadh, the Saudi capital, where the president was photographed participating in a traditional sword dance. Around the same time, Mr. Kushner personally helped negotiate a 10-year deal for Saudi Arabia to buy more than $110 billion worth of US weapons. Prince Mohammed was named crown prince in June.
Mr. Kushner and Prince Mohammed communicated regularly and informally via text message and addressed each other by first name. After Khashoggi’s murder, Mr. Kushner Prince Mohammed at the White House despite intelligence reports showing he was involved in the plan to execute the journalist.
In a move widely interpreted as an attempt to protect the prince, Mr. Trump kept those reports secret throughout his tenure. They were unsealed this year by President Biden, who has called Saudi Arabia a “pariah” and has taken a much cooler approach to the kingdom than his predecessor.
While in the White House, Mr. Kushner devoted much of his energies to trying to recruit Arab states at a grand bargain to provide economic benefits to the Palestinians in exchange for Palestinian concessions to Israel. While that effort was no more successful than previous attempts at peace in the Middle East, his talks with the Emirates and a few neighbors eventually yielded the narrower Abraham Accords about normalizing relations with Israel.
mr. Kushner has adopted a low profile since leaving the White House. With his wife, Ivanka Trump, and their children, he moved to Miami, outside the media spotlight of New York and Washington. There he established Affinity in recent months.
He has told employees he has no desire to re-enter politics. To build on pacts he helped negotiate in government, Mr. Kushner founded the Abraham Accords Institute for Peace, a non-profit organization that aims to expand trade ties between Israel and its Arab neighbors.
Mr. Kushner also hopes his new company, Affinity, will find opportunities in cross-border investment in the Middle East, said the person with knowledge of the company’s plans. An important area of focus, this person said, is building investment relationships between Israel and Saudi Arabia.
