CHEYENNE, Wyo. (AP) — U.S. Sens. John Barrasso and Mike Enzi and others have introduced a bill to block President Barack Obama from going around Congress to implement a national energy tax.

The proposal would prohibit the issuance of new carbon pollution standards through a presidential memorandum for existing coal-fired power plants.

Barrasso says such a move would increase energy bills, close coal plants and decrease economic opportunities. The Republican says his bill will require the Obama Administration to get congressional approval before moving forward with regulations.

Enzi says it's another example of Obama using the EPA as a weapon against the energy industry.
