Story highlights CNN obtained the leaked proposal over the weekend

The Clean Power Plan requires states to meet specific carbon emission reduction standards based on their individual energy consumption

Washington (CNN) Environmental Protection Agency Administrator Scott Pruitt announced Monday his agency's plans to withdraw the Clean Power Plan, the sweeping Obama-era rule regulating greenhouse gas emissions.

While speaking in Kentucky at an event with Senate Majority Leader Mitch McConnell, Pruitt said he will sign the proposed rule repealing Obama's plan Tuesday.

"When you think about what that rule meant, it was about picking winners and losers. Regulatory power should not be used by any regulatory body to pick winners and losers," he said at the event. "The past administration was using every bit of power and authority to use the EPA to pick winners and losers and how we generate electricity in this country. That's wrong."

CNN obtained a copy of the leaked proposal to repeal the milestone Clean Power Plan, the outcome of President Donald Trump's executive orders calling for the review of the plan and questions the legality of the original rule.
