President Trump signed an executive order Tuesday scrapping a controversial Environmental Protection Agency rule that expanded the agency's jurisdiction over the nation's waterways during the second term of former President Obama.
The regulation, known as the Waters of the U.S. rule, broadened the definition of the type of water body that would fall under EPA's formidable clean water enforcement powers, making everything from streams to ditches and watering holes subject to the EPA's and Army Corps of Engineers' oversight.
The rule has been a top target for the GOP on Capitol Hill for more than two years, with Republicans and some Democrats opposing the regulation, which was renamed the Clean Water Rule after being made final by EPA. Trump vowed to repeal the regulation during his campaign. The executive order is meant to be a sign that he intends to keep his promises to supporters, who want to rein in the Obama administration's overreaching rules.
