The Senate voted Thursday to block a measure by Sen. Mike Lee Michael (Mike) Shumway LeeMcConnell shores up GOP support for coronavirus package McConnell tries to unify GOP Davis: The Hall of Shame for GOP senators who remain silent on Donald Trump MORE (R-Utah) that would have repealed former President Obama’s landmark water pollution rule.

The amendment would have prohibited funding in a major spending bill from being used by the Army Corps of Engineers to enforce the Clean Water Rule, also known as Waters of the United States.

The rule was developed alongside the Environmental Protection Agency (EPA). Multiple federal courts have put it on hold, and the Trump administration is working to repeal it.

Senators voted 62-34 to table the amendment, effectively blocking it.

Republicans have consistently opposed the water rule, but 20 GOP senators voted with most Democrats to block Lee’s amendment, since it would break a deal that Senate Appropriations Committee leaders made to avoid controversial policy provisions in spending bills.

“I have no doubt about it, I can't find many people on this side of the aisle who approved of the Waters of the United States regulation of the previous administration,” Senate Majority Leader Mitch McConnell Addison (Mitch) Mitchell McConnellFEC flags McConnell campaign over suspected accounting errors Poll: 59 percent think president elected in November should name next Supreme Court justice Mark Kelly: Arizona Senate race winner should be sworn in 'promptly' MORE (R-Ky.) said on the Senate floor.

“It's on the way to the ash heap of history right now under this administration. So this is not about Waters of the United States or whether we are for it or against it. This is about whether we want to get away from annual omnibus appropriation bills, and this is the first test here,” he said, referring to the process of passing spending bills as a massive package, written in conference negotiations.

Lee nonetheless pushed ahead.

“It is not unusual to have policy in an appropriations bill. It happens with some regularity.”

Lee referenced a 2016 resolution in which 53 senators voted to repeal the water rule, which was enough to pass the measure. The House also voted to repeal it, but Obama vetoed the repeal.

The Obama-era water rule would have redefined the federal government’s authority over bodies of water and exerted authority over small waterways like ponds and headwaters.

The GOP and numerous industries say it effectively gave the government power over large swaths of both water and land, including dry areas.
