Donald Trump Jr.’s role in the Trump Tower Russia meeting: Here’s how it happened, and why it matters. It’s all based on a bombshell June 2016 email sent by Rob Goldstone, a trusted family intermediary. The email said a Kremlin insider offered to provide dirt on Hillary Clinton. Trump Jr. replied within minutes. Quote, If it’s what you say, I love it, unquote. Goldstone, who is an entertainment publicist, says the information was given to him by his client, Emin Agalarov, one of Russia’s biggest pop stars. Emin has had a very public friendship with President Trump. “You’re a winner. You’re a champ.” “You’re an absolute winner. You proved everybody wrong.” Goldstone suggests that Emin got his information from his dad, Aras Agalarov, a Putin-linked Russian real estate tycoon. Goldstone goes on to claim that Aras may have gotten his information from a high-ranking Kremlin official. When the meeting was exposed, President Trump helped write a reply on behalf of his son, saying it was primarily about the adoption of Russian children. But on Aug. 5, Trump in his starkest terms yet said the meeting was actually to get information on an opponent. That statement and others are being scrutinized by the Mueller team to see if they were part of an effort to deceive investigators.
