Former House Speaker Newt Gingrich appeared on national TV yesterday, on the Fox News program hosted by Laura Ingraham, to discuss a variety of issues. Among them was Pennsylvania joining the Regional Greenhouse Gas Initiative (RGGI) carbon tax scheme. Gingrich said Gov. Wolf’s executive order forcing the state into RGGI will “punish” PA for producing natural gas. He said Wolf is hopelessly locked in because the left wants to punish Pennsylvanians “in the name of their ideology.”
