Elon Musk sent an email threatening to sue Twitter staff who leak confidential information, report says

• Elon Musk sent an email threatening to sue Twitter staff who leak confidential information.
• He gave the employees until 5 p.m. on Saturday to sign a pledge, a source told Insider.

Elon Musk has threatened to sue the "few" Twitter employees who keep leaking confidential information to the media, according to reports.

Zoë Schiffer of Platformer obtained a copy of the email on Saturday but didn't post the document online because "Twitter is doing everything it can to catch sources," she tweeted.

According to Schiffer's tweets, Musk wrote in the email: "As evidenced by the many detailed leaks of confidential Twitter information, a few people at our company continue to act in a manner contrary to the company's interests and in violation of their NDA."

He added: "This will be said only once: If you clearly and deliberately violate the NDA that you signed when you joined, you accept liability to the full extent of the law & Twitter will immediately seek damages."

Staff had until 5 p.m. PT on Saturday to sign a pledge, according to the email.

A Twitter source also told Insider that Musk had sent the email to Twitter staff.

One Twitter user quickly quipped: "Love that the email asking staffers to not leak information, got leaked."

The company is facing four lawsuits filed by former employees, accusing it of various unfair practices following their dismissals.

Four plaintiffs from the lawsuits being represented by Shannon Liss-Riordan spoke at a media conference in San Francisco on Thursday. It came before a court hearing for action brought by five former employees who alleged that Twitter did not provide adequate notice before its mass layoffs.

Many of them expressed their support for former colleagues with families or those who didn't feel comfortable appearing at the event.

Twitter didn't immediately respond to a request for comment from Insider.
