Erik Prince, the private security contractor and the former head of Blackwater, arranged the meeting, which took place on Aug. 3, 2016. The emissary, George Nader, told Donald Trump Jr. that the princes who led Saudi Arabia and the United Arab Emirates were eager to help his father win election as president. The social media specialist, Joel Zamel, extolled his company’s ability to give an edge to a political campaign; by that time, the firm had already drawn up a multimillion-dollar proposal for a social media manipulation effort to help elect Mr. Trump.

It is unclear whether such a proposal was executed, and the details of who commissioned it remain in dispute. But Donald Trump Jr. responded approvingly, according to a person with knowledge of the meeting, and after those initial offers of help, Mr. Nader was quickly embraced as a close ally by Trump campaign advisers — meeting frequently with Jared Kushner, Mr. Trump’s son-in-law, and Michael T. Flynn, who became the president’s first national security adviser. At the time, Mr. Nader was also promoting a secret plan to use private contractors to destabilize Iran, the regional nemesis of Saudi Arabia and the Emirates.
After Mr. Trump was elected, Mr. Nader paid Mr. Zamel a large sum of money, described by one associate as up to $2 million. There are conflicting accounts of the reason for the payment, but among other things, a company linked to Mr. Zamel provided Mr. Nader with an elaborate presentation about the significance of social media campaigning to Mr. Trump’s victory.

Mr. Nader also visited Moscow at least twice during the presidential campaign as a confidential emissary from Crown Prince Mohammed of Abu Dhabi, according to people familiar with his travels. After the election, he worked with the crown prince to arrange a meeting in the Seychelles between Mr. Prince and a financier close to President Vladimir V. Putin of Russia.
