Twitter has removed the verification check mark on the main account of The New York Times, one of CEO Elon Musk’s most despised news organizations.

The removal comes as many of Twitter’s high-profile users are bracing for the loss of the blue check marks that helped verify their identity and distinguish them from impostors on the social media platform.

Musk, who owns Twitter, set a deadline of Saturday for verified users to buy a premium Twitter subscription or lose the checks on their profiles. The Times said in a story Thursday that it would not pay Twitter for verification of its institutional accounts.

Early Sunday, Musk tweeted that the Times’ check mark would be removed. Later he posted disparaging remarks about the newspaper, which has aggressively reported on Twitter and on flaws with partially automated driving systems at Tesla, the electric car company, which he also runs.

Other Times accounts such as its business news and opinion pages still had either blue or gold check marks on Sunday, as did multiple reporters for the news organization.

“We aren’t planning to pay the monthly fee for check mark status for our institutional Twitter accounts,” the Times said in a statement Sunday. “We also will not reimburse reporters for Twitter Blue for personal accounts, except in rare instances where this status would be essential for reporting purposes,” the newspaper said in a statement Sunday.
