Earlier this week, President Obama signed a law to provide health care to thousands of Marine veterans and their families who were exposed to contaminated water at Camp Lejeune between 1957 and 1987. Retired Marine Jerry Ensminger was one of them. His daughter died of leukemia he believes was caused by the contamination. For fifteen years, Ensminger has led the fight to get help for sick veterans and their families. And he says it’s not over yet.
