U.S. Sen. Chuck Grassley, R-Iowa, says the proposed Waters of the United States rule could influence voters in November's midterm elections. The Environmental Protection Agency wants to expand the Clean Water Act, to the protests of many in agriculture.
Grassley says the record of Democratic senate candidate Bruce Braley, who currently serves in the U.S. House, may hinder his chances.
"Braley said that he was against Waters USA and then when there was a bill in the House to stop it, he was the only one in the Congressional delegation to vote against the bill," Grassley says.
Grassley adds many farmers he's spoken to oppose the rule, though the Iowa Corn Growers Association endorsed Braley.
Braley faces Republican state Sen. Joni Ernst in the November.
