Government watchdog groups are calling on congressional committees to release the names of Trump political appointees who have “burrowed” into career civil service positions over concerns they may attempt to “sabotage” the Biden administration.

The letter was signed by government watchdog groups Accountable.US, American Oversight, Public Citizen, Campaign for Accountability, Government Information Watch and the Government Accountability Project. Accountable.US has also filed 60 public records requests to various government agencies, seeking the release of reports regarding political appointees who have been transferred to permanent career positions.

“In his final days as president, Donald Trump refused to work with the incoming administration to deal with historic crises he only made worse, and instead made it easier to pack the government with his crony political appointees,” Kyle Herrig, president of Accountable.US, said in a statement to Salon. “If any former Trump political operative is now working to sabotage and obstruct action against the pandemic and recession, the public deserves to know their names.”
