EXCLUSIVE — A State Department-backed “disinformation” tracker under congressional investigation is shielding key details about its operations from the Washington Examiner despite blacklisting conservative media outlets for having “opaque ownership structures.”

The Global Disinformation Index has faced heightened scrutiny from Republican lawmakers over the British group’s covert efforts to defund websites it disagrees with, and it is also at the center of a new lawsuit against the State Department over the agency wiring $100,000 to GDI. While GDI brands itself as a “nonpartisan” proponent of transparency, that didn’t stop its two affiliated nonprofit groups in the United States from providing the Washington Examiner with heavily redacted copies of their newly filed 2022 financial disclosures, a maneuver tax experts warn likely violates federal law.
