Far-left billionaire George Soros has funneled more than $50 million to a network of Iran-sympathizer groups whose members have gained significant sway within the Biden White House — pushing to defang US sanctions on Tehran while advocating for a renewed nuclear deal.

A Post examination of Soros’ Open Society Foundations records shows the progressive kingmaker has given a staggering $46.7 million since 2016 to the International Crisis Group, a lefty think tank tied to an alleged Iranian plot to manipulate US policy.

Robert Malley, the former US special envoy to Iran now under FBI investigation for his alleged mishandling of classified material, was the ICG’s president until he joined the Biden administration in 2021.

“Soros has continually funded organizations that act as apologists for the Iranian regime – downplaying their severe human rights abuses while working to advance Iranian propaganda,” Gabriel Noronha of the Polaris National Security think tank told The Post.

Soros cash funded the ICG’s formation in 1994, and the billionaire was a trustee for years before handing the seat to his son and ideological heir Alexander Soros, 38, in 2018.
