The Democratic candidate for one of Pennsylvania‘s U.S. Senate seats, John Fetterman, turned a few heads last week when he expressed a newfound love for fracking. He previously disavowed the practice on several occasions.

“I support fracking,” Fetterman told NBC News. “I supported the energy security we should have in the United States. I’ve always supported [it], as long as it’s done environmentally sound and making sure that we’re not contaminating our waterways.”
