Republicans on the House Oversight and Government Reform Committee opened a probe into alleged organized efforts to inject bias into Wikipedia entries and the organization’s responses.
Chair James Comer (R-Ky.) and Rep. Nancy Mace (R-S.C.), chair of the panel’s subcommittee on cybersecurity, information technology, and government innovation, on Wednesday sent an information request on the matter to Maryana Iskander, chief executive officer of the Wikimedia Foundation, the nonprofit that hosts Wikipedia.
The request, the lawmakers said in the letter, is part of an investigation into “foreign operations and individuals at academic institutions subsidized by U.S. taxpayer dollars to influence U.S. public opinion.”
The panel is seeking documents and communications about Wikipedia volunteer editors who violated the platform’s policies, as well as the Wikimedia Foundation’s efforts to “thwart intentional, organized efforts to inject bias into important and sensitive topics.”
“Multiple studies and reports have highlighted efforts to manipulate information on the Wikipedia platform for propaganda aimed at Western audiences,” Comer and Mace wrote in the letter.
They referenced a report from the Anti-Defamation League about anti-Israel bias on Wikipedia that detailed a coordinated campaign to manipulate content related to the Israel-Palestine conflict and similar issues, as well as an Atlantic Council report on pro-Russia actors using Wikipedia to push pro-Kremlin and anti-Ukrainian messaging, which can influence how artificial intelligence chatbots are trained.
“[The Wikimedia] foundation, which hosts the Wikipedia platform, has acknowledged taking actions responding to misconduct by volunteer editors who effectively create Wikipedia’s encyclopedic articles. The Committee recognizes that virtually all web-based information platforms must contend with bad actors and their efforts to manipulate. Our inquiry seeks information to help our examination of how Wikipedia responds to such threats and how frequently it creates accountability when intentional, egregious, or highly suspicious patterns of conduct on topics of sensitive public interest are brought to attention,” Comer and Mace wrote.
The lawmakers requested information about “the tools and methods Wikipedia utilizes to identify and stop malicious conduct online that injects bias and undermines neutral points of view on its platform,” including documents and records about possible coordination of state actors in editing, the kind of accounts that have been subject to review, and and of the panel’s analysis of data manipulation or bias.
The Wikimedia Foundation did not immediately respond to a request for comment.
Wikipedia has long faced accusations of its entries having a political bias, with the right-leaning Manhattan Institute releasing a report in 2024 that found Wikipedia entries are more likely to attach a negative sentiment to right-leaning terms.
