Senior U.S. officials were worried. Since the early months of the Trump administration, Jared Kushner, the president's son-in-law and Middle East adviser, had been having private informal conversations with Prince Mohammed bin Salman, the favorite son of Saudi Arabia's king.
Given Kushner's political inexperience, the private exchanges could make him susceptible to Saudi manipulation, said three former senior U.S. officials. In an effort to tighten practices at the White House, a new chief of staff tried to reimpose longstanding procedures stipulating that National Security Council staff members should participate in all calls with foreign leaders.
But even with the restrictions in place, Kushner, 37, and Crown Prince Mohammed, 33, kept chatting, according to three former White House officials and two others briefed by the Saudi royal court. In fact, they said, the two men were on a first-name basis, calling each other Jared and Mohammed in text messages and phone calls.
The exchanges continued even after the Oct. 2 killing of Jamal Khashoggi, the Saudi journalist who was ambushed and dismembered by Saudi agents, according to two former senior U.S. officials and the two people briefed by the Saudis.
As the killing set off a firestorm around the world and U.S. intelligence agencies concluded that it was ordered by Crown Prince Mohammed, Kushner became the prince's most important defender inside the White House, people familiar with its internal deliberations say.
Kushner's singular bond has helped draw President Donald Trump into an embrace of Saudi Arabia as one of his most important international allies.
But the ties between Kushner and Crown Prince Mohammed did not happen on their own. The prince and his advisers, eager to enlist U.S. support for his hawkish policies in the region and for his own consolidation of power, cultivated the relationship with Kushner for more than two years, according to documents, e-mails and text messages reviewed by the New York Times.
A delegation of Saudis close to the prince visited the United States as early as the month Trump was elected, the documents show, and brought back a report identifying Kushner as a crucial focal point in the courtship of the new administration. He brought to the job scant knowledge about the region, a transactional mind-set and an intense focus on reaching a deal with the Palestinians that met Israel's demands, the delegation noted.
