The House approved an amendment to legislation Friday that would prevent the White House from imposing a carbon tax without congressional approval.

The lower chamber agreed to Rep. Steve Scalise’s (R-La.) amendment by a 237-176 vote, with 12 Democrats crossing the aisle to support it.

The amendment was added to an underlying bill that would require Congress to OK regulations that carry a $100 million economic impact or greater. That bill is dead in its tracks in the Democratic-controlled Senate, and the White House has threatened to veto it.

Scalise’s measure doesn’t have much of a practical implication, as Congress — not the executive branch — is tasked with approving new taxes.
