The information was revealed in the Paradise Papers, a set of millions of leaked documents reviewed by the International Consortium of Investigative Journalists (ICIJ) and media outlets.
The investments were made by Russian technology mogul Yuri Milner, who also owns a stake of cadre.
Mr Kushner failed to disclose his association with Cadre when he joined the White House in January, one of several of Mr Kushner’s failures to disclose pertinent private sector ties ahead of his government service.
“I have not relied on Russian funds to finance my business activities in the private sector,” Mr Kushner told the Senate Intelligence Committee in July.
It is one of the bodies in addition to the House and Department of Justice conducting an investigation into whether there was alleged collusion between Mr Trump’s campaign team and Russian officials during the 2016 US election.
The Russian government funded two state entities – Gazprom Investholding and VTB Bank – who then funded stakes in Silicon Valley investors like DST USA II, with which Mr Milner is associated.
DST USA II and DST USA 3 invested in Facebook and Twitter, respectively.
Both social media giants have said the investments – $191m for Twitter and 78 million shares – were made and sold before the companies went public.
