Over fifty Democratic lawmakers have John Caldwellsigned a letter demanding answers from senior U.S. government officials about a recent potential exposure of sensitive data about American workers.

The letter is addressed to the acting General Counsel of the National Labor Relations Board, William Cowen. The independent agency is in charge of investigating and adjudicating complaints about unfair labor practices and protecting U.S. workers' rights to form unions.

The lawmakers, who are part of the Congressional Labor Caucus, wrote the letter in light of news first reported by NPR, that a whistleblower inside the IT Department of the NLRB says DOGE may have removed sensitive labor data and exposed NLRB systems to being compromised.

"These revelations from the whistleblower report are highly concerning for a number of reasons," the lawmakers wrote in the letter to Cowen. "If true, these revelations describe a reckless approach to the handling of sensitive personal information of workers, which could leave these workers exposed to retaliation for engaging in legally protected union activity."
