Senator Sherrod Brown is asking the federal government to put more money into the investigation of a child cancer cluster in Clyde.
Brown says Ohio agencies leading the investigation need more money to get to the bottom of the cancer cases that are centered around Sandusky County and the town of Clyde.
Since 1996, 35 children have been diagnosed with several forms of cancer in a 12-mile wide circle just south of Lake Erie.
So far, there's no known cause.
Brown says in a letter sent to the U.S. Centers for Disease Control and Prevention and the Environmental Protection Agency that the children and families within the cancer cluster deserve answers.
Families from the area have been asking the government to spend more money on childhood cancer research.
