The question was about climate change ― the man-made global crisis that Ryan Zinke, as a Montana state senator, once urged President Barack Obama to take action on, but in recent years has become willfully blasé about.

“It appears that the world is laughing at the United States’ stance as it relates to climate change,” CNN correspondent René Marsh told the secretary of the interior, along with acting Environmental Protection Agency Administrator Andrew Wheeler, at a Dec. 11 briefing on EPA’s proposal to gut an Obama-era clean water rule. ”What is your response?”

Marsh was referring specifically to protesters disrupting and laughing derisively during a U.S. panel promoting coal, oil and natural gas at the United Nations climate talks in Poland.

Zinke, the muscle of President Donald Trump’s “energy dominance” agenda, wasn’t about to be forced into a discussion of global warming ― not in a room full of like-minded, fossil fuel-friendly Republicans. Instead, he stepped to the microphone and pounded his oil drum. “I don’t think OPEC is laughing,” he said.

The former Montana congressman and Navy SEAL then reached for his bag of well-aged energy talking points. It was a speech he’d rolled out dozens of times and fine-tuned over his 21 scandal-plagued months as chief steward of America’s public lands. He said it’s “better to produce energy in this country under reasonable regulation than to watch it get produced overseas with none.” He invited any doubters in the room to join him on a tour of “environmental disasters” that he’d seen in the Middle East and Africa. And he told people he never wanted their children to have to fight overseas for a commodity available right here at home.

In closing, Zinke said he was “proud” the United States is now the largest oil and gas producer in the world ― and “proud of the fact that we’re going to get even better.”

The full-throated endorsement of big oil, Zinke’s second in as many weeks, would prove to be one of his last public addresses as the agency’s chief. It was met with uproarious applause. It was also a fitting coda for a man who, by virtually every measure, failed to “create a conservation stewardship legacy, second only to Teddy Roosevelt,” which topped his list of priorities.

Days after the EPA press conference, Trump announced Zinke would step down at the end of the year. Zinke maintains it was a personal decision. In his resignation letter to Trump, he blamed his departure on “vicious and politically motivated attacks.” But reporting by The Washington Post and others indicates that the embattled secretary, who’s faced nearly 20 federal investigations into his conduct and policy decisions, had known for weeks that he was being forced out.

In many ways, Zinke’s final month highlights the real legacy he’s likely to leave behind: not of stewardship but of cozying up to the industries he was tasked with regulating, rolling back safeguards for the environment and endangered species, and opening millions of acres of public land to drilling and mining.

Sen. Tom Udall (N.M.) was one of 15 Democratic senators who voted to confirm Zinke to the post. That decision, he said, was based on Zinke’s assurances that he understood the agency’s central mission, and his pledge to lead in the spirit of Roosevelt.

“It is abundantly clear from his time as Interior Secretary that those promises were empty, meaningless, and untrue,” Udall told HuffPost in an email. “His tenure was deeply destructive and I would not vote to confirm him again knowing what we know now ― that he always intended to carry the torch for the Trump administration’s campaign of relentless attacks on our public lands, waters, Tribal sovereignty, and the environment.”

Not quite Teddy

Zinke has pitched himself as a public land champion in the mold of the 26th president since at least 2009, when he served as a state senator in Montana. Somewhat bizarrely, his top spokeswoman, Heather Swift, who didn’t start working for Zinke until he ran for Congress in 2014, takes credit on her resume for developing this Roosevelt-style “brand,” writing that it earned her boss “praise from the energy sector, sportsmen’s groups, natural resources trade associations, and traditionally left-leaning conservation organizations alike.”

This image is part of what Trump liked about the fifth-generation Montanan. And it no doubt helped Zinke sail through Senate confirmation. Upon being sworn in, Zinke pledged to “faithfully uphold Teddy Roosevelt’s belief that our treasured public lands are ‘for the benefit and enjoyment of the people.’” A day later, he arrived at the agency’s headquarters wearing a 10-gallon cowboy hat and riding a horse ― an apparent tribute to his hero. In his first speech to Interior staff, he talked about the importance of stewardship and plans of a “bold” Roosevelt-style reorganization to address future challenges. He promised to “fight” Trump on the budget proposal, which at the time called for a 10 percent cut in agency funding.

Instead, Zinke went to bat for industry, prioritizing ending a supposed “war” that the Trump administration says the Obama administration waged on fossil fuels. He embraced budget proposals that called for slashing funding for land acquisition and conservation programs, while promoting increased drilling and extraction on public lands. And he quickly proved frustrating for sporting and conservation groups that had high hopes for him.

Collin O’Mara, president of the nonprofit National Wildlife Federation, initially saw Zinke’s nomination as a signal that Trump “intends to keep his promises to America’s hunters, anglers and outdoor enthusiasts.” When others turned on Zinke, O’Mara continued to give him a chance to follow through on his stewardship promises and responsibility.

Ultimately, though, Zinke lost O’Mara’s support. One day after the resignation announcement, O’Mara published a blistering opinion piece in The Washington Post, writing that “Zinke’s dogged pursuit of unfettered fossil-fuel extraction makes James Watt’s disastrous tenure look timid.” Watt, President Ronald Reagan’s interior chief, is widely considered among the most anti-environment Cabinet appointees in American history.

O’Mara told HuffPost that the National Wildlife Federation was committed to trying to make progress with Zinke on certain issues, but there was “a growing realization that conservation was always going to be an afterthought” to energy production.

“The divide between the rhetoric and the reality just got wider and wider,” said O’Mara, adding that the potential he saw in Zinke never manifested on the sixth floor of Interior headquarters.

The Interior Department employs more than 70,000 people and manages 500 million acres of federal land — roughly one-fifth of the U.S. — including the 59 national parks. The agency can at times seem to be at odds with itself. It has the bifurcated task of preserving and protecting public lands for future generations while also setting policies that govern the exploitation of their natural resources.

The job of any secretary is to find a happy medium. Less than a year in, Zinke declared that he and his team had succeeded in “striking the right balance.” But a roundtable that he hosted six months later suggested the opposite was true ― and that Zinke knew it. At that May meeting to get input on his sweeping proposal to reorganize the agency, Zinke promised representatives of more than two dozen outdoor sporting and conservation organizations that he would make a “grand pivot” away from energy development and toward species and habitat conservation, as E&E News reported.

In other words, the grand pivot never arrived.

Theodore Roosevelt IV, a great-grandson of the late president who has blasted the interior secretary for invoking his ancestor, said Zinke’s “bad angels won out.”

“He was marching lockstep with what the president wanted him to do,” Roosevelt said. “It’s unfortunate.”

Zinke “disrespected Interior’s stewardship mission & its dedicated career staff,” David Hayes, Interior’s deputy secretary under Obama, said on Twitter.

The Interior Department did not respond to HuffPost’s request for an interview with the secretary.

The oil industry’s best friend

The lengths to which Zinke went to ensure a better future for coal, oil, gas and mining interests are impressive. He overturned an Obama-era moratorium on new coal leases on federal land and scrapped a hydraulic fracturing rule meant to protect public health. He rolled back an Obama-era rule limiting the amount of methane, a powerful greenhouse gas, that can be released from oil and gas operations on federal and tribal lands. He proposed opening nearly all U.S. waters to offshore drilling, and moved to weaken key offshore safety regulations adopted in the aftermath of the devastating Deepwater Horizon oil spill. In fiscal 2018, Interior offered more than 12.8 million federal acres for oil and gas leasing, “triple the average offered during President Barack Obama’s second term,” The New York Times reported. That’s an area more than twice the size of Maryland. Some of those leases sold for as little as $1.50 per acre, according to a Times investigation.

The oil and gas industry, a top donor to Zinke’s congressional campaigns, applauded the secretary at nearly every turn. Thomas Pyle, president of the American Energy Alliance, said Zinke “served the country in a way we haven’t seen from the federal government’s land use agency since the days of President Ronald Reagan.”

“Most importantly, Zinke has unleashed American energy potential by tapping into the vast resource reserves on federal lands and opening up previously unexplored areas to development,” Pyle said in a statement.

Along the way, Zinke peddled industry talking points, misinformation and climate change denial. In a May 2017 op-ed he argued that natural areas can benefit from resource extraction. He claimed California’s catastrophic wildfires have “nothing to do with climate change” ― then later said “of course” it was a factor, without acknowledging the role humans play. And he repeatedly cast doubt on the latest federal climate assessment, which found that greenhouse gas emissions have put the planet on a trajectory toward catastrophic climate change.

He also became a pincushion of ethics probes and unfavorable headlines. He insisted a special flag fly above the agency’s headquarters each time he walked through the door, which his team claimed was “a major sign of transparency.” He accused 30 percent of Interior employees of not being “loyal to the flag,” and told an oil and gas industry association that “our government should work for you.” And he called a top Democratic lawmaker a drunk after he called for Zinke’s resignation.

In the end, Zinke’s exit was much like his entrance. He said little about protecting America’s natural heritage, but he spoke glowingly of oil. His final acts as secretary included pushing the administration one step closer to opening Alaska’s fragile Arctic National Wildlife Refuge to oil and gas drilling, which he said “stands out among the most impactful” Interior accomplishments in terms of “bolstering America’s economic strength and security.” (That claim about the economy is highly debatable.) He unveiled a plan to dismantle Obama-era protections for the greater sage grouse, a move that would open up millions of acres of the declining game bird’s habitat to energy and mineral development. When a U.S. Geological Survey assessment identified an ocean of previously undiscovered oil and gas reserves in the Permian Basin under Texas and New Mexico, Zinke rejoiced. “Christmas came a few weeks early,” he said.

There were moments in his final month in office when Zinke sounded like a modern-day Daniel Plainview, the fictional oilman played by Daniel Day-Lewis in the film “There Will Be Blood.” “We’ve gotten a lot better as industry,” Zinke told the National Petroleum Council at its Dec. 4 meeting, quickly correcting himself: “You’ve gotten a lot better.” He told the room he was “bullish” on energy, saying he expected that within two years the U.S. would be “marching real close to” producing 14 million barrels of oil per day. He stressed that Interior needs to “be better at emphasizing” why domestic energy production is “environmentally, morally, economically” the “right path.”

It was as if he were interviewing for his next gig. And that very well may have been the case. Politico reported in November that Zinke had reached out to various parties about potential jobs, including with Fox News and in the energy industry. Zinke’s team dismissed the report as fake news.

O’Mara, the National Wildlife Federation president, expects Zinke will end up working in the fossil fuel sector.

“He decided that it was in his interest to focus on fulfilling industry’s desires over the mission of the department,” O’Mara said.

In a parting interview with Fox News’ Bret Baier, Zinke was asked about the perceived one-sidedness of his agenda. Zinke dismissed such claims as “bunk” and attempted to do some damage control, highlighting achievements he said the media refuses to talk about. His list was largely the same one from a year before.

“We’ve opened up millions of acres for public access, hunting and fishing. We’ve opened up 39 wildlife refuges,” he told Fox. Doing so is not unique to this administration. In its final two years alone, the Obama administration expanded hunting and fishing opportunities on at least 34 refuges.

“We expanded wilderness,” Zinke said. But only one wilderness area — Sabinoso Wilderness in New Mexico — expanded as a result of Zinke’s actions. And that deal was first announced in 2016, well before his tenure, and made possible thanks to a private donation of 3,595 acres. Zinke simply accepted the land donation.

“We’ve initiated wildlife corridors, first ever,” Zinke said. In February he signed an order to identify and protect big game migration corridors. That initiative has been widely celebrated, but the BLM has continued to offer oil and gas leases in key habitat.

“I’ve withdrawn minerals in sensitive areas,” Zinke said. In October, he extended a mining ban on 30,000 acres in Montana’s Paradise Valley, just north of Yellowstone National Park. It is one of several cases of Zinke protecting public lands in his home state as he’s worked to open up land elsewhere. (There is wide speculation that Zinke has future political aspirations, perhaps for Montana governor.) Last year, for example, Interior reversed an Obama-era decision and renewed leases for a Chilean firm to mine nickel and copper just outside Minnesota’s Boundary Waters Canoe Area Wilderness.

“What they don’t say,” Zinke said of his critics, “is, actually, we are one of the leading conservationists.”

It’s a bold claim for any administration, let alone one that in the midst of global biodiversity and climate crises has prioritized fossil fuel development and worked to chip away at bedrock conservation laws, namely the Endangered Species Act and the Migratory Bird Treaty Act.

In recent months, as the cloud of ethical troubles darkened and rumors swirled that his future was in peril, Zinke took to accusing critics on the left of being “angry,” “intolerant,” “uninformed” and unwilling to “look at the actual facts.” He echoed that sentiment in his resignation letter to Trump, saying that “to some, truth no longer matters.”

But the truth about Zinke is that he isn’t the Rooseveltian conservationist he sold himself as. Donning a cowboy hat doesn’t make a person a cowboy any more than flying a special flag over an office makes someone transparent.

“He talked a really good game going in and then just was a good soldier,” Tawney, the president of Backcountry Hunters & Anglers, said. “You can’t go in there and talk about how you’re a Theodore Roosevelt Republican, a student of Theodore Roosevelt, and do the things that he did.”

Somewhere, Tawney said, America’s conservationist president “is shaking his fist.”
