OSIJEK, Croatia (AP) — Dozens of suspected Nazi war criminals and SS guards collected millions of dollars in U.S. Social Security benefits after being forced out of the United States, an Associated Press investigation has found.

The payments, underwritten by American taxpayers, flowed through a legal loophole that gave the U.S. Justice Department leverage to persuade Nazi suspects to leave the U.S. If they agreed to go, or simply fled before deportation, they could keep their Social Security, according to interviews and internal U.S. government records.
