WASHINGTON— The Center for Biological Diversity sued Trump’s Office of Management and Budget and Office of Information and Regulatory Affairs today seeking the schedules of key members of the administration.

The lawsuit seeks the calendars of Russell Vought, director of the Office of Management and Budget, Stuart Levenbach, the U.S. chief statistician, and Mark Paoletta and Jeffrey Clark, the current and former acting administrators of OIRA.

Although many agencies from past administrations routinely published the calendars of high-level officials on their websites, Trump’s OMB stated it would not release any records for at least three years. That means Americans won’t know the details of how these offices affected the public until well after Trump leaves office.

“Russ Vought and other Trump cronies have inflicted enormous damage on our environment and the federal civil service with virtually no accountability. That needs to stop,” said Ivan Ditmars, an attorney at the Center. “The architects of Project 2025 continue unleashing their rabid anti-environmental, fascistic beliefs on the entire nation and the public has a right to know what they’re hiding. The damage they’re causing behind the scenes every day should set off alarm bells everywhere.”

Together these records will likely reveal the roles these top political appointees play in the most consequential environmental rollbacks to date. Vought, a key author of Project 2025, has spearheaded government-wide efforts to dismantle environmental protections.

Levenbach, who formerly worked for fossil fuel giant Baker Hughes, served as the chief of staff for National Oceanic and Atmospheric Administration in the first Trump administration, where he tried to kill a key climate report. He returned to OMB in the first months of the current Trump administration, overseeing the dismantling of environmental programs.

Paoletta, who in Trump’s first term helped justify diverting funds to build the border wall, is not only the general counsel of OMB but also chief legal officer at the Consumer Financial Protection Bureau and acting administrator of OIRA.

Clark was once Trump’s top environmental lawyer and later became a central figure in efforts to overturn the 2020 election. In his short stint as acting administrator of OIRA, Clark played a key role in the repeal of the greenhouse gas endangerment finding.

Since the start of Trump’s second term, OIRA has been operating without a formally nominated administrator. The office was run by Clark until November 2025, when the Center requested an investigation by the Government Accountability Office into whether he had violated the Federal Vacancies Reform Act.

Shortly after that, Clark was reassigned to the role of “associate administrator” and Paoletta was named as the new acting director of OIRA.

In March 2025 the Center sent Freedom of Information Act requests seeking the calendars of Vought, Clark and Levenbach. OIRA received the Center’s request for Paoletta’s calendars in February 2026, but similarly, has released no records in response.

“It’s ludicrous for Americans to have to wait more than three years to learn even the most basic workings of the government under Trump,” said Ditmars. “Every day, the Trump administration takes a sledgehammer to our transparency laws, making it harder for the public to understand how the government is allowing special interest elites to maximize their corrupt actions with impunity.”

Today’s lawsuit was filed in the U.S. District Court for the District of Columbia.
