Former Senator George Allen and Planet Gore contributor Marlo Lewis write in Forbes:

The agency is making federal decisions without the consent of Congress.
The U.S. Environmental Protection Agency is carrying out one of the biggest power grabs in American history. The agency has positioned itself to regulate fuel economy, set climate policy for the nation and amend the Clean Air Act–powers never delegated to it by Congress. It has done this by declaring greenhouse gas emissions a danger to public health and welfare, in a proceeding known as the “endangerment finding.”
On Tuesday the U.S. Senate will debate and vote on Alaska Sen. Lisa Murkowski’s resolution of disapproval to overturn the endangerment finding. The resolution is absolutely necessary to restore democratic accountability in climate policymaking.
If allowed to stand, the EPA’s endangerment finding will trigger a regulatory cascade through multiple provisions of the Act. America could be burdened with a regulatory regime more costly than any climate bill Congress has rejected or declined to pass, yet without the people’s representatives ever voting on it.

The rest here.
