An American held by Japan as a prisoner of war during World War II and forced to work in a copper mine has been invited to accompany President Barack Obama on his historic visit to Hiroshima this week, a U.S. veterans group said. Jan Thompson, the head of the American Defenders of Bataan and Corregidor Memorial Society, said Sunday by email that the group has chosen 94-year-old Daniel Crowley of Simsbury, Connecticut, and submitted his name to the White House.
