Edie Rubinowitz reports on the controversy over San Jose Island, located 60-miles south of Panama City. United States military used the island during World War Two for testing chemical weapons and their eoffects on soldiers. The island is still littered with unexploded bombs containing chemical agents. The U.S. leased the island from Panama's government from 1944 to 1948 but says it has no obligation to clean up the munitions. Critics say the Chemical Weapons Convention of 1997 requires the U.S. to do so.
