Billionaire George Soros donated at least $10.5 million to Hillary Clinton’s 2016 presidential campaign. But the two families are chummy beyond that and they don’t even try to hide it.

Soros’ son Alexander posted a selfie of himself with Chelsea Clinton on his Instagram Story on Tuesday. The photo was taken at the Gordon Parks Foundation June 6 gala, which, according to the website, honored specific “individuals who have enriched our lives.” The younger Soros was one of the honorees.
