WASHINGTON (AP) — A government watchdog says more than 130 suspected Nazi war criminals, SS guards, and others who may have participated in the Third Reich’s atrocities during World War II collected $20.2 million in Social Security benefits.

The findings are detailed in a report by the inspector general of the Social Security Administration scheduled for public release Tuesday. The Associated Press obtained a copy of the report.

The IG’s report comes seven months after an AP investigation revealed benefits were paid to former Nazis after they were forced out of the United States.

AP’s investigation stoked outrage on Capitol Hill. President Barack Obama late last year signed into law a measure that bars suspected Nazi war criminals from receiving the benefits.

Congresswoman Carolyn Maloney, a New York Democrat, requested the IG’s report.
