Did This Progressive Democrat Billionaire Fund the Ferguson Riots?:
"Per a report from the Washington Times, Soros “gave at least 33 million in one year” to groups that emboldened the rabble-rousers in Ferguson, using data the Times obtained from tax filings from Soros’ Open Society Foundations.
Starting in August of last year, buses of rabble-rousers, including Communist groups, arrived in Ferguson, Mo, funded largely with money traced back to Soros.
Communist front groups like Missourians Organizing for Reform and Empowerment, the Organization for Black Struggle (they’re for  black struggle?), and Dream Defenders were all involved in forming the “Hands Up Coalition,” promoted as a so-called “grassroots” organization in Missouri."
