Billionaire activist and major Hillary Clinton donor George Soros used his nonprofits to fund opposition research on critics of radical Islam and to discredit the Israeli government, according to more than 2,500 documents hackers put online.

Soros’ Open Society Foundations gave $200,000 to the Center for American Progress, a liberal think tank, to conduct “high-quality opposition research” to fight against “anti-Muslim xenophobia and to promote tolerance,” according to the Daily Caller, which first reported on the swiped documents.

American Progress was founded by John Podesta, Clinton’s campaign chief.

The DC Leaks Web site said the hack attack on Soros was “launched by American hacktivists who respect and appreciate freedom of speech, human rights and government of the people.”

But US security experts are blaming the leak on Russian hackers, according to Bloomberg News.
