Caitlyn Jenner told Elon Musk that she is worried about his safety after “The Twitter Files” came out about the Hunter Biden laptop.

In a tweet on Friday, the ex-Olympian said:

@elonmusk I hope you are surrounded by massive security and in an extremely safe undisclosed location – you just became public enemy number one to some very very bad people, I pray for your safety and thank you for your bravery! We need more @elonmusk in our society!!!

Musk, the new owner of Twitter, also said that he probably should “increase his security” during a live interview on Twitter Space on Saturday. One speaker asked him if he was feeling any pressure since he released documents about Twitter’s decision to censor a 2020 New York Post story about a laptop linked to President Biden’s son Hunter.

The billionaire, who bought the social media site on October 27, said that he was trying to build trust by letting people see the internal documents. It’s not clear if Musk gave them to independent journalist Matt Taibbi, but he got them and posted internal communications and other information about the company’s decisions at the time.

Here’s what Musk said in a Tweet:

Twitter acting by itself to suppress free speech is not a 1st amendment violation, but acting under orders from the government to suppress free speech, with no judicial review, is.

An insider is reportedly said to have reached out to Musk for his comment.
