Twitter on Thursday suspended the accounts of journalists who cover the social media platform and its new owner Elon Musk, among them reporters working for The New York Times, Washington Post, CNN, Voice of America and other publications.

The company hasn’t explained to the journalists why it took down the accounts and made their profiles and past tweets disappear. But Musk took to Twitter on Thursday night to accuse journalists of sharing private information about his whereabouts that he described as “basically assassination coordinates.” He provided no evidence for that claim.

The sudden suspension of news reporters followed Musk’s decision Wednesday to permanently ban an account that automatically tracked the flights of his private jet using publicly available data. That also led Twitter to change its rules for all users to prohibit the sharing of another person’s current location without their consent.

Several of the reporters suspended Thursday night had been writing about the new policy and Musk’s rationale for imposing it, which involved his allegations about a stalking incident he said affected his family on Tuesday night in Los Angeles.

The official account for Mastodon, a decentralized social network billed as an alternative to Twitter, was also banned. The reason was unclear, though it had tweeted about the jet tracking account.

“Same doxxing rules apply to ‘journalists’ as to everyone else,” Musk tweeted Thursday. He later added: “Criticizing me all day long is totally fine, but doxxing my real-time location and endangering my family is not.”

“Doxxing” refers to disclosing online someone’s identity, address, or other personal details.

The Washington Post’s executive editor, Sally Buzbee, called for technology reporter Drew Harwell’s Twitter account to be reinstated immediately. The suspension “directly undermines Elon Musk’s claim that he intends to run Twitter as a platform dedicated to free speech,” Buzbee wrote. “Harwell was banished without warning, process or explanation, following the publication of his accurate reporting about Musk.”

CNN said in a statement that “the impulsive and unjustified suspension of a number of reporters, including CNN’s Donie O’Sullivan, is concerning but not surprising.”

“Twitter’s increasing instability and volatility should be of incredible concern for everyone who uses Twitter,” CNN’s statement added. “We have asked Twitter for an explanation, and we will reevaluate our relationship based on that response.”

Another suspended journalist, Matt Binder of the technology news outlet Mashable, said he was banned Thursday night immediately after sharing a screenshot that O’Sullivan had posted before his own suspension.

The screenshot showed a statement from the Los Angeles Police Department sent earlier Thursday to multiple media outlets, including The Associated Press, about how it was in touch with Musk’s representatives about the alleged stalking incident, but that no crime report had yet been filed.

“I did not share any location data, as per Twitter’s new terms. Nor did I share any links to ElonJet or other location tracking accounts,” Binder said in an email. “I have been highly critical of Musk but never broke any of Twitter’s listed policies.”

Binder said a message he received while trying to access his Twitter account showed that his suspension was permanent. But Musk later suggested the penalty would last a week in response to a question about his suspension of former ESPN and MSNBC host Keith Olbermann.

Late Thursday, Musk briefly joined a Twitter Spaces conference chat hosted by journalist Kate Notopoulos of Buzzfeed. He reiterated his claims that the journalists Twitter banned were “doxxing” him when they were reporting on the jet tracking accounts being banned.

“There is not special treatment for journalists,” Musk said, after being asked by the Post’s Drew Harwell if he had a connection between the stalking incident and posting of real-time information.

“You dox, you get suspended, end of story,” he added, before abruptly signing out. The Spaces ended abruptly shortly after 9 p.m. Pacific time.

“Sorry it appears the Space cut out, screen went suddenly blank on my end and everyone got booted,” host Notopoulos tweeted at 9:14 p.m. Pacific.

Another suspended reporter, Steve Herman of Voice of America, said he assumes he was banned “because I was tweeting about other journalists being suspended for tweeting about accounts being booted that had linked to the Elon Jet feed.”

The suspensions come as Musk makes major changes to content moderation on Twitter. He has tried, through the release of selected company documents dubbed as “The Twitter Files,” to claim the platform suppressed right-wing voices under its previous leaders.

He has promised to let free speech reign and has reinstated high-profile accounts that previously broke Twitter’s rules against hateful conduct or harmful misinformation, but also has said he would suppress negativity and hate by depriving some accounts of “freedom of reach.”

The nonprofit Committee to Protect Journalists, which defends journalists around the world, said Thursday night it was concerned about the suspensions.

“If confirmed as retaliation for their work, this would be a serious violation of journalists’ right to report the news without fear of reprisal,” the group said.

European Union Commissioner Vera Jourova, who heads up the 27-nation bloc’s work on values and transparency, also weighed in.

“News about arbitrary suspension of journalists on Twitter is worrying,” she tweeted. Existing EU media rules and new digital regulations taking effect next year require “respect of media freedom and fundamental rights.”

Jourova said, “@elonmusk should be aware of that. There are red lines. And sanctions, soon.”

The Germany government added more criticism. The Foreign Ministry tweeted that it’s “got a problem” with not being able to follow the suspended accounts and added that “press freedom must not be switched on and off at will.”

Spokesman Christofer Burger said the ministry opened an account on Mastodon “to ensure we remain reachable.”
