The Founding Fathers intended all lands owned by the federal government to be sold. William Perry Pendley in the National Review

William Perry Pendley is the author of Project 2025’s Department of Interior (DOI) chapter. A climate science denier with significant connections to the fossil fuel industry, Pendley served unlawfully as Trump’s Acting Director of the Bureau of Land Management from 2019-2021. Pendley is known for his extreme position advocating for the sell-off of public lands, asserting that “the Founding Fathers intended all lands owned by the federal government to be sold.”

Pendley was never confirmed by the Senate, having failed to secure the votes of even some Republicans given his extensive history challenging BLM itself and the 57 potential conflicts of interest that he would be required to recuse himself from. Then-Interior Secretary Dave Bernhardt gave Pendley the authority of acting director and repeatedly extended his tenure despite widespread opposition. In September 2020, Pendley was ordered to leave his post by a federal judge who found he had already illegally served in the role for more than a year, but Pendley refused to leave and asserted, “I have not been ousted. I’m still at my desk. I have the confidence of the president of the United States. I have the confidence of the Secretary.”

Pendley is the author of the Department of the Interior (DOI) chapter of Project 2025’s Mandate for Leadership, which centers around cutting environmental protections, disseminating the “regulatory regime”, and opening protected federal lands for “economic use.” Throughout the chapter, Pendley calls for:

– Rewarding extractive industry allies by dramatically weakening environmental requirements for projects on federal lands, so that industry can maximize production of logging, oil & gas drilling, fracking, and coal mining.

– Urging Congress to kneecap the National Environmental Policy Act (NEPA), which requires federal agencies to assess the environmental effects of their proposed actions.

Reinstating SO 3352 (National Petroleum Reserve—Alaska), which opens public lands to oil and gas extraction and reinstate President Trump’s 2020 Alaska Roadless Rule to allow for timber logging and massive infrastructure projects in the Tongass National Forest.

– Pushing Congress to repeal the Antiquities Act of 1906, which protects cultural and natural resources on federal lands from destruction.

– Rescinding the Endangered Species Act rules defining Critical Habitat and Critical Habitat Exclusions” from the Biden Administration.


Pendley’s proposals to limit the National Environmental Policy Act ​​(NEPA) were described by the current Interior Secretary Deb Haaland as “inconsistent with protecting public health and the environment.”

Further, Pendley (again) proposed relocating the BLM again as an “immediate action” to take if Trump were to take office. The first move scattered about 300 D.C.-based BLM roles across twelve states and resulted in only about 23% of the staff who needed to relocate accepting their reassignments, dramatically reducing the number of Black and Asian BLM employees in the process. A performance audit by the U.S. Government Accountability Office (GAO) concluded that “BLM [had] not substantially followed key practices for effective agency reforms relevant to relocating employees,” and gave four executive action recommendations to improve, none of which the BLM implemented.

On top of dismissing the staffing issues presented by the relocation, Pendley defended the choice to move the BLM into a building that also housed a Chevron corporate office, a branch of the state’s lead energy lobbying firm the Colorado Oil and Gas Association, independent natural gas exploration company Laramie Energy, and additional oil companies. The Public and Environmental History Center at Colorado State University noted, “People whose businesses are based on extractive uses of public lands, including ranchers and energy interests, are among the major proponents of the BLM reorganization because they believe it will give them more access to and possibly more influence over the people who have power over their businesses.”

Pendley first worked in the Interior Department in the Reagan administration under then-Secretary James G. Watt, who went on to lead the Mountain States Legal Foundation (MSLF), a group launched to fight environmental regulations with the financial backing of beer magnate Joseph Coors, who also backed the Heritage Foundation. Pendley would become the longtime president of MSLF, leading the group as it represented oil, timber, and other extractive interests in efforts “attacking environmental protections and designations.” MSLF has also been criticized for consistently undermining Native American rights.

While in office, Pendley called the Trump administration’s controversial cuts to Grand Staircase-Escalante and Bear Ears national monuments “insufficient”, and offered Maine and Oregon as examples of states where more national monuments could be reduced.
