Clinton's big question: To ban or not to ban fracking?

Democratic nominee Hillary Clinton plans to eliminate a decade-old provision that exempts fracking from government environmental regulations if she is elected president in November, while hedging on whether she would actually ban the drilling practice.

Trevor Houser, Clinton’s energy adviser, told a policy forum held on the sidelines of the Democratic National Convention Wednesday that removing the so-called “Halliburton loophole” will be a priority under a Clinton administration.
