Elon Musk breaks silence on Twitter, posts a picture with the Pope

Elon Musk on Friday night broke his nine-day silence on Twitter, the social media platform he is trying to buy for $44 billion, posting a picture of him meeting Pope Francis on Thursday.

The world's richest person tweeted a picture where he can be seen standing next to the pope, captioning it: "Honored to meet @pontifex yesterday." Musk's four teenage boys are also pictured, but not his 18-year-old transgender daughter who, on June 20 sought to change her name and sever ties with him. Musk has a total of eight children.

The purpose and location of Musk's meeting with the pope were not immediately clear.

Last month, Musk said there were "still a few unresolved matters" on the deal to buy Twitter, including the number of spam users on the system and the coming together of the debt portion of the deal.
