Conservatives critical of Elon Musk are accusing the platform he owns of censoring them, CNN reports.

Political activist Laura Loomer sparked an online debate within the Right about work visas known as H1-Bs, which Musk supports. Loomer now claims her account has been unverified and demonetized, accusing Musk of being a “free speech fraud.”

Meanwhile, another conservative activist, Charles C. Johnson, claims X banned his account because he “embarrassed” Musk by writing about his father’s alleged involvement with an emerald mine, something Musk has long denied. (Neither this nor Loomer’s accusations have been substantiated.)

Elon has long publicly supported free speech, posting that it’s “the bedrock of democracy.” But Musk has also been accused of silencing people on the platform, notably in 2022 when X temporarily suspended journalists covering the suspension of an account tracking his jet.

X didn’t immediately respond to a request for comment.
