Charges for aiding and abetting the murder of thousands of Hungarians during the Nazi occupation of Hungary during World War II are being prepared by Hungarian prosecutors against 92-year-old Hungarian-American businessman George Soros.

According to a source at the prosecutor’s office in Budapest, Hungary, Soros is expected to be charged with “knowingly and willfully” aiding and abetting the murder of Jewish Hungarians in Budapest from September 1942 to January 1943.

The government of Prime Minister Viktor Orban has been working to bring historical crimes committed by Hungarian Nazi collaborators to justice, and it is believed that Soros has been using his extensive resources to “hide in plain sight” for decades.

Prime Minister Orban has been warning about Soros’ corrosive influence on society for decades. “Europe must not succumb to the Soros network,” wrote Orbán recently.

Soros was born to a Jewish family in Hungary in 1930, and survived the Holocaust by collaborating with the Nazis. He has expressed a total lack of remorse for his actions, telling 60 Minutes in 1988 that if he didn’t do it, somebody else would have anyway.

Soros was been missing since at least March 5, shortly after news leaked about the impending charges. He was expected to attend a conference on his recent work on African education however he did not arrive.

The prosecution considers Soros fit to stand trial despite his advanced age, the prosecutor’s office said, however the case will be on hold until he is arrested.

Soros founded the Open Society Foundation in 1993 to help promote far-left values and open borders around the world. Laura Silber, a spokesperson for the foundation, told USA TODAY that the claim Soros aided and abetted Nazis is “100% false.”

US-based fact checkers have regularly defended Soros from claims that he was a Nazi during his teenage years. However, these same fact checkers are funded in part or wholly by Soros and they have failed to identify this conflict of interest while reporting on Soros.
