A former editor at Wikipedia says that the online encyclopedia engaged in a multiyear smear campaign against conservative radio host Mark Levin.

T. D. Adler previously edited for Wikipedia under the name “The Devil’s Advocate” and currently writes under an alias to mitigate blowback for criticizing the website. He wrote in a piece published on Breitbart that Wikipedia’s editors have been purposely undermining Levin’s credibility with edits since he accused then-President Barack Obama of using “police-state tactics” in 2017.
