Congress investigates Wikipedia for 'foreign manipulation'

The House Oversight Committee, led by Comer and Mace, is investigating the Wikimedia Foundation for alleged coordinated editing by foreign nation-state actors and U.S.-funded academic institutions to bias Wikipedia content. The probe targets violations of platform policies by volunteer editors injecting propaganda, including pro-Russia and anti-Israel narratives.

Comer and Mace, in a letter to Wikimedia CEO Iskander, requested documents on editors breaching neutrality rules and the Foundation’s response to organized bias. They cited an ADL report on anti-Israel content manipulation and an Atlantic Council study exposing pro-Kremlin messaging affecting AI training.

“Multiple studies… highlighted efforts to manipulate information on the Wikipedia platform for propaganda aimed at Western audiences,” Comer and Mace wrote.
