The Commerce Department has stripped away protections against political interference from its scientific integrity policy, a move that has alarmed former federal officials and data experts who warn the change could compromise the reliability of critical government statistics.
The department quietly revised its policy on August 19, 2026, removing provisions that had explicitly prohibited attempts to manipulate data collection and scientific analysis for political purposes. The updated policy governs all Commerce Department agencies, including the Census Bureau, the National Oceanic and Atmospheric Administration, and the Bureau of Economic Analysis.
The timing of the revision has drawn scrutiny. The policy change occurred one day after the Census Bureau released an unusual report containing claims about non-U.S. citizen voting. According to NPR, that report came from a team with connections to a think tank established by individuals who served in President Trump's first administration.
Nancy Potok, who previously served as deputy director at the Census Bureau and held positions at the Commerce Department, characterized the modifications as significant. The eliminated provisions represent "a major change that eliminates the guardrails against political interference in the statistical and scientific data products of the department," Potok told NPR.
The January 2025 version of the policy, issued shortly before Trump's second inauguration, had contained explicit safeguards. That iteration prohibited interference with scientific work "against well-accepted scientific methods and theories or without scientific justification." It mandated that research findings "are not suppressed, delayed, or altered for political purposes and are not subjected to inappropriate influence."
The August 19 revision eliminated that language entirely. The updated policy also removed a statement identifying "protection from inappropriate influence" as a fundamental characteristic of scientific integrity.
Robert Santos, who served as Census Bureau Director under President Biden, noted the proximity between the policy revision and the controversial voting report. "It's entirely possible that this was done to reconcile the Department of Commerce and the administration's own actions by publishing an external partisan document about voting on the Census Bureau website," Santos told NPR. "The publishing exemplifies inappropriate influence. It was not transparent, and it didn't even include career staff experts."
The concerns extend beyond a single policy document. Potok has monitored how statistical agencies have implemented a regulation known among federal data specialists as the "Trust Regulation," which stems from legislation passed in 2018. That rule mandates that statistical agencies maintain objectivity and produce information that remains "impartial and free from undue influence and the appearance of undue influence."
"The fact that there is a conscious effort to revise the department administrative orders and not incorporate things that are in the [Trust Regulation], instead of going in the other direction, is definitely troubling and needs some explanation," Potok told NPR.
The policy change arrives as the Census Bureau faces multiple challenges. In June 2026, the Trump administration prohibited the agency from employing a decades-old method for protecting data privacy. That decision has postponed the publication of new American Community Survey estimates and may ultimately limit the granularity of statistics available for smaller geographic areas and populations, including those in rural regions.
The administration has also indicated that substantial modifications to the 2030 census may be forthcoming. The decennial count determines congressional representation and guides the distribution of federal funding to communities nationwide for the subsequent decade.
These developments unfold against the backdrop of significant workforce reductions. The Trump administration's cuts to federal employment have triggered departures among the bureau's specialized personnel, including those with expertise in statistics and economics.
Beth Jarosz, vice president of the Association of Public Data Users, expressed concern about the revised policy's new framework for investigating alleged violations, which diminishes the involvement of department attorneys. "There's room for interference because the way that the new rule is structured leaves lots of opportunities to put pressure on staff to act in a certain way, to decide things in a certain way or to come to certain conclusions," Jarosz told NPR. "It certainly seems like the guardrails, if they are still there at all, they are much weaker than they used to be."
Representatives from the Commerce Department and Census Bureau did not provide responses to NPR's inquiries seeking comment on the policy revision.
The Commerce Department's agencies produce information that affects numerous aspects of American life, from weather forecasting through the National Oceanic and Atmospheric Administration to economic indicators tracked by the Bureau of Economic Analysis, which monitors the nation's gross domestic product.
