The Senate on Wednesday confirmed Ryan Zinke’s nomination to lead the Interior Department by a 68 to 31 vote.

Zinke will head a department that manages a fifth of the land in the United States, about 500 million surface acres, a total that doesn’t include millions more acres and natural resources underground. Interior has an enormous environmental footprint, with agencies that decide how resources such as coal are managed and which animals are eligible for listing under the Endangered Species Act.

Republicans called the former Montana congressman and Navy SEAL a strong choice for Interior, as an avid hunter with western roots who understands how federal regulations on the cultivation of coal, natural gas and minerals on public lands can hurt corporate revenue and reduce jobs.

“I believe Representative Zinke is a solid choice for this position,” said Sen. Lisa Murkowski (R-Alaska), chair of the Senate Energy and Natural Resources Committee that approved his nomination in a partisan vote more than a month ago. “While we may not agree on every issue … I believe he will work with us in a thoughtful manner that is reflective of a true partnership.”

Democrats were wary of Zinke despite his declaration that he believes humans contribute to climate change. “Man has had an influence,” he said under questioning by Sen. Bernie Sanders (I-Vt.). Zinke’s assertion that the level of human contribution is unknown, despite the near unanimous opinions of climate scientists who say it’s overwhelming, didn’t help. Liberals worried that Zinke would open more land to exploitation at the expense of wildlife and their declining habitat.

Zinke’s confirmation came more than a month after the committee’s approval partly because of politics, and Murkowski and Cantwell’s speeches on the Senate floor reflected the broad partisan divide. Zinke was approved by a 16-6 committee vote largely along party lines. All of the committee’s 12 Republicans voted in Zinke’s favor.

Zinke told the committee that one of his first priorities would be to fix the crumbling infrastructure at parks under the National Park Service. He said President Trump’s ambitious infrastructure spending plans should “prioritize the estimated $12.5 billion in backlog of maintenance and repair” at hundreds of national parks such as Yosemite National Park, the Mall, Memorial Bridge and the George Washington Memorial Parkway.
