France’s state-owned railway, accused of being complicit in transporting Jews and others to concentration camps during World War II, is fighting back against efforts in Congress to allow Holocaust survivors to sue its American subsidiary in U.S. courts.

This month, Société Nationale des Chemins de fer Français subsidiary SNCF America Inc. has brought in reinforcements to defeat the bill, called the Holocaust Rail Justice Act. In total, the SNCF now has a half-dozen Washington-area lobby shops working on the issue. The latest, Hogan Lovells, notified Congress on July 13 that it is providing lobbying help to the group.
