Facebook CEO Mark Zuckerberg, wife meet with Pope Francis

Pope Francis met with Facebook founder and CEO Mark Zuckerberg and Zuckerberg's wife, Priscilla Chan, at the Vatican on Monday.

Vatican spokesman Greg Burke says one topic of discussion was "how to use communication technologies to alleviate poverty, encourage a culture of encounter, and make a message of hope arrive, especially to those most in need."

The atmosphere appeared informal, with the chat taking place in the Santa Marta residence, the guest house in Vatican City where the pope lives.

"We talked about last week's earthquake and how the Facebook community in Italy and around the world has come together to help people recover and rebuild," Zuckerberg said in a Facebook post.

In another post, Zuckerberg said he and his wife expressed to the pope their admiration for his "message of mercy and tenderness."

The Facebook founder said the pope's "warmth and kindness" was palpable and described the meeting as one he and his wife will never forget.

Zuckerberg and Chan also met with Italian Prime Minister Matteo Renzi on Monday.

Zuckerberg then held a town hall Q&A session in Rome, which was streamed online via Facebook Live.
