In the letter, Comer and Mace referenced a report from the Anti-Defamation League, in which they allege that Wikipedia coordinated a campaign to manipulate entries related to the War in Gaza, which they allege advanced “antisemitic and anti-Israel information.”

"As our research showed earlier this year, antisemitism and anti-Israel bias on Wikipedia are a significant problem. We welcome the House Committee on Oversight and Government Reform opening an investigation into this issue and thank Rep. James Comer for his leadership effort to address this hate," in a statement released by ADL on Wednesday, Aug. 27.

The lawmakers also referenced a report from the think tank, Atlantic Council, which alleged that pro-Russia actors used Wikipedia to push pro-Kremlin messaging on its platform.
