For the last several years, billionaire philanthropist George Soros has been quietly financing a revolution in criminal justice reform, doling out tens of millions of dollars to progressive candidates in district attorney races throughout the country amid movements to abolish bail and defund the police.

Working with an activist attorney, Soros, 91, mainly funnels cash through a complicated web of federal and state political action committees as well as non-profits from coast to coast, public records show.

Last year, the Foundation to Promote Open Society, a nonprofit in Soros’ orbit, gave $3 million to the Community Resource Hub for Safety and Accountability, according to a recent report. The group provides resources to “local advocates and organizations working to address the harm of policing in the US.”
