This is not Wall Street either(slight sarcasm), it's just an individual American citizen giving money to the Clinton's, and their son-in-law. Nothing to see here, folks.
'WHEN HILLARY CLINTON’S son-in-law sought funding for his new hedge fund in 2011, he found financial backing from one of the biggest names on Wall Street: Goldman Sachs chief executive Lloyd Blankfein.
The fund, called Eaglevale Partners, was founded by Chelsea Clinton’s husband, Marc Mezvinsky, and two of his partners. Blankfein not only personally invested in the fund, but allowed his association with it to be used in the fund’s marketing.'

'The decision for Blankfein to invest in Hillary Clinton’s son-in-law’s company is just one of many ways Goldman Sachs has used its wealth to forge a tight bond with the Clinton family. The company paid Hillary Clinton $675,000 in personal speaking fees, paid Bill Clinton $1,550,000 in personal speaking fees, and donated between $250,000 and $500,000 to the Clinton Foundation. At a time when Goldman Sachs directly lobbied Hillary Clinton’s State Department, the company routinely partnered with the Clinton Foundation for events, even convening a donor meeting for the foundation at the Goldman Sachs headquarters in Manhattan.'
