Twitter suddenly suspended a host of the nation’s preeminent tech journalists on Thursday, many of whom have reported about billionaire Elon Musk’s chaotic leadership at the social media giant in recent weeks.

The accounts for The New York Times’ Ryan Mac, The Washington Post’s Drew Harwell, CNN’s Donie O’Sullivan, Mashable’s Matt Binder and independent journalist Aaron Rupar all disappeared Thursday evening, as did several others.

All of those reporters have reported deeply about Musk’s $44 billion takeover of Twitter, the fallout after he laid off half of its employees and the company’s decision to ban, then un-ban, then re-ban an account that tracked Musk’s private plane flights.

Aaron Rupar told NBC’s Ben Collins he had “no idea” why the suspension happened. Other suspensions rolled in later in the evening, including for political commentator Keith Olbermann.

Journalists who cover Elon Musk have been suspended on Twitter tonight: @Donie O'Sullivan from CNN, Aaron Rupar and the Washington Post's @drewharwell.

Rupar tells me he has "no idea" why it happened.

A message on the accounts simply says they have been suspended for violating Twitter’s rules.

Mac, writing from a secondary account on Twitter, said he was given “no warning” before the suspension and has not been contacted in any way by the company.

“I report on Twitter, Elon Musk and his companies,” Mac wrote. “And I will continue to do so.”

Some folks have asked so will try to answer here:
-This is the notification on my account.
-I was given no warning.
-I have no email or communication from the company about the reason for suspension.
-I report on Twitter, Elon Musk and his companies. And I will continue to do so. pic.twitter.com/Fz14nStH7U

Twitter’s head of trust and safety, Ella Irwin, told the Verge the company wouldn’t comment on any specific suspensions but did say “we will suspend any accounts that violate our privacy policies and put other users at risk.”

“We don’t make exceptions to this policy for journalists or any other accounts,” Irwin said, pointing to Twitter’s updated policy of sharing “live location information.”

Twitter has already been drastically reshaped since Musk formally took ownership of the company in October. He has disbanded teams that address hate speech and civil rights abuses and demanded that the company update policies on the fly to target accounts and critics that irk him.

The New York Times reported this week that Musk and his advisers have been looking at stiffing former employees of severance pay in an effort to cut costs. Twitter also hasn’t paid rent for its San Francisco headquarters, or for many of its other global offices, in weeks, hoping to renegotiate lease terms.
