Energy Secretary Rick Perry on Tuesday approved the first permit under his tenure to ship natural gas to overseas markets, even as large U.S. manufacturers are warning the Trump administration that those exports could lead to skyrocketing energy prices in America.

“This announcement is another example of President Trump’s leadership in making the United States an energy dominant force,” Perry said in approving the Golden Pass export terminal in Texas for shipping liquefied natural gas abroad. “This is not only good for our economy and American jobs, but also assists other countries with their energy security.”
