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 worlds richest person tweeted a picture where he can be seen standing next to the pope, captioning it: "Honored to meet @pontifex yesterday." Musks four teenage boys are also picture. Musk has a total of eight children. The purpose and location of Musks 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.
