Email records show that in 2015 former Vice President Joe Biden apparently attended a dinner with some of his son Hunter’s dubious business partners. Ukrainian, Russian, and Kazakhstani business partners all gathered for a dinner at Washington, D.C.’s Cafe Milano, a restaurant known for attracting the Capitol’s elite.

According to reports, Hunter Biden was currently being paid over $80,000 a month from Burisma Holdings, a Ukrainian energy firm.

The New York Post reports:

The next day, Hunter received an email from Vadym Pozharskyi, an executive of the Ukrainian energy company Burisma, to thank him for introducing him to his father.

The guest list prepared by Hunter three weeks before the Café Milano dinner included Russian billionaire Yelena Baturina and her husband, corrupt former Moscow mayor Yury Luzhkov, who since has died. Baturina wired $3.5 million on Feb. 14, 2014, to Rosemont Seneca Thornton LLC, a Delaware-based investment firm co-founded by Hunter and Devon Archer, a former adviser to Secretary of State John Kerry.

The wires were flagged in suspicious activity reports provided by the Treasury to a Senate Republican inquiry into Hunter last year by the Homeland Security and Governmental Affairs Committee.

Hunter told guests before the dinner that his father would be attending. In one email, he appears to use his role on the board of World Food Program USA as a cover story for the evening’s true purpose of introducing his father to his business associates.

Emails between Biden and Karloutsos indicate the two were working hard to conceal Vice President Biden’s involvement. However, the former VP has repeatedly claimed he has never had a hand in any family member business dealings.
