Around May 2014, Burisma Holdings, a Ukrainian oil company announced that it had added Hunter Biden (US Vice-President Joe Biden's son) to its board of directors.
This caused a small controversy in the media. The Federalist published a few reasons to be skeptical that it actually happened:
The company’s website is…rough, at best, and the domain does not appear to have even been registered until 2010 even though the company was allegedly founded in 2002 and incorporated in 2006. And as recently as July of 2013, the website was not even written in English.
Basic information about the business is also difficult to find. Joe Weisenthal of Business Insider noted on Twitter that the company lacked a profile in Bloomberg, an extensive database of business information, and had no Wikipedia presence whatsoever. Businessweek contained only a brief blurb about the company, stating that it was incorporated in 2006 and based in Cyprus.
Since then, the issue seems to have been forgotten in the media.
Is there any independent source (not from the company's own website) that confirms that Hunter Biden works in Ukraine for Big Oil?
