The video shows the future President Donald Trump attending a dinner with an Azerbaijani-Russian family who became Trump’s business partners in Las Vegas in June 2013. It also shows their publicist, Rob Goldstone, who would later send Donald Trump Jr. the emails that have brought the eldest Trump son to the center of the controversy over possible collusion between Trump campaign associates and Russia.

Goldstone, who is also seen in the video talking with Trump, claimed in the 2016 emails that damaging information against Hillary Clinton surfaced after a meeting between someone Goldstone described as “the Crown prosecutor of Russia” and Aras Agalarov, an Azerbaijani-Russian billionaire with ties to Russian President Vladimir Putin. Goldstone then offered to set up a call between the younger Trump and Emin Agalarov, the billionaire’s son and a pop star Goldstone represents, to discuss the information.
