The House Oversight Committee opened an investigation into the Wikimedia Foundation, ordering records by September 10 tied to alleged anti-Israel bias and foreign manipulation of Israel-related Wikipedia content.
The letter, signed by Republican Reps. James Comer and Nancy Mace, directs Wikimedia CEO Maryana Iskander to produce materials covering January 1, 2023 to the present.
Requests fall into six buckets:
- records on possible nation-state coordination in editing
- records on coordination within academic institutions or other organized efforts
- Wikipedia’s Arbitration Committee conduct cases and actions
- identifying characteristics for editors already subject to Arbitration Committee actions—names, IP addresses, registration dates, and activity logs
- editorial policy documents on neutrality, bias, and discipline
- any internal or third-party analyses of manipulation or bias related to antisemitism and conflicts with Israel
Congress has placed Wikimedia under federal investigation for including criticism of Israel in Wikipedia articles, requesting the information of individuals who contributed.

The committee cites recent work by the Anti-Defamation League and the Atlantic Council’s DFRLab alleging coordinated anti-Israel activity and pro-Kremlin content shaping.
The letter frames the probe as guarding against “foreign operations and individuals at academic institutions… to influence US public opinion” and asks how Wikipedia detects and stops bias while preserving a neutral point of view.
Notably, the letter ended with “thank you for your attention to this important matter,” a notable phrase recently as used by President Donald Trump to end his Truth Social posts and letters.
Wikipedia is built by volunteer editors who add and revise content using published, reliable sources under three core policies: neutral point of view, verifiability, and no original research. Disputes are worked out on article “talk” pages and resolved by consensus, and administrators can protect pages and block disruptive accounts. Serious conduct cases go to the community-run Arbitration Committee, while the Wikimedia Foundation hosts the platform and enforces sitewide terms and privacy rules.
