A pair of House Republicans is moving forward with an investigation that will seek to reveal the identities of Wikipedia editors who have edited articles to include information that portrays Israel negatively. The representatives asked Wikimedia's CEO, Maryana Iskander, for "assistance in obtaining documents and communications regarding individuals (or specific accounts) serving as Wikipedia volunteer editors who violated Wikipedia platform policies as well as your own efforts to thwart intentional, organized efforts to inject bias into important and sensitive topics."

Of chief concern to the legislators is investigating Wikipedia's handling of content related to Israel. They cited a report from the Anti-Defamation League (ADL), a pro-Israel lobbying group, which the legislators said "raised troubling questions about potentially systematic efforts to advance antisemitic and anti-Israel information in Wikipedia articles related to conflicts with the state of Israel."

The ADL report makes the allegation that 30 "bad-faith" Wikipedia editors, whose identities are not public, were collaborating to edit pages about the Israel-Palestine conflict by "spotlighting criticism of Israel and downplaying Palestinian terrorist violence and antisemitism," and in the process violating Wikipedia's commitment to neutrality.
