The U.S. 6th Circuit Court of Appeals in January upheld a decision to revoke Johann Leprich's citizenship.
In September, Leprich's lawyer asked a federal judge to order his client released, citing a 2001 U.S. Supreme Court decision requiring the freeing of those still held for deportation six months after a removal order.
The Justice Department said it released Leprich on Monday because Romania, Hungary and Germany refused to accept him, despite high-level meetings with officials from those countries
Leprich, an ethnic German born in Romania, joined the Nazi military organization Waffen SS in 1943 and served as a guard at Mauthausen concentration camp in Nazi-occupied Austria, court records say. About 119,000 people were killed at Mauthausen, including political prisoners, Jews, and Soviet, Dutch and Czech prisoners of war.
He immigrated to the U.S. after World War II and became a U.S. citizen in 1958.
