Interior Secretary Ryan Zinke said Tuesday he is prepared to scale back his controversial proposal to massively expand drilling in federal waters off the U.S. coasts.

“What we are seeing is more production onshore than offshore,” Zinke said during testimony before the Senate Energy and Natural Resources Committee, seemingly downplaying offshore oil and gas prospects. “There is no question offshore oil and gas drilling is riskier. It’s riskier for a number of reasons, one is environmentally.”
