To the strains of Lee Greenwood’s song “Proud to be an American,” President Trump took the stage at the American Farm Bureau convention in Austin last week and boasted about repealing water pollution control regulations across the U.S. The Obama Administration imposed the Waters of the U.S. Rule in 2015 to protect intermittent streams and scattered wetlands that are not adjacent to rivers or lakes. But what Trump did not tell the farm convention is that the Obama-era regulations already exempted most farming practices, as did previous federal and state wetlands protection rules.
