“I very much disagree with Secretary Moniz that criticism for his Department’s lack of urgency in approving LNG export applications is ‘B.S.,’ ” Gardner said on Monday. “The only player that doesn’t believe that the Department of Energy needs to expedite permits to export LNG is the Department of Energy. Secretary Moniz’s belligerent tone on the issue shows just how out of touch he truly is.”

Gardner, who is running for Senate against Sen. Mark Udall (D-Colo.), said more than 20 applications are pending approval to export LNG.

The House has passed legislation that would force the Department of Energy to streamline its approval process, but the Senate hasn’t taken up Gardner’s bill.

“It’s not just industry that has voiced concerns over the current application approval process,” Gardner said. “The House of Representatives passed my bill to expedite the approval process for LNG export applications with overwhelming bipartisan support, and our allies from around the world have emphasized the importance of United States LNG exports time and time again.”

Europe heavily relies on Russia for natural gas, but with the threat of sanctions over Russia’s invasion of Crimea, some lawmakers have called on the United States to help out U.S. allies who don’t want to be beholden to Russian President Vladimir Putin.

Lawmakers who don’t want to increase natural gas exports argue it would increase domestic energy prices for consumers.
