Facebook founder and CEO Mark Zuckerberg leaves a meeting with Senator John Cornyn (R-TX) in his office on Capitol Hill on September 19, 2019 in Washington, DC.

Facebook CEO Mark Zuckerberg made the surprising call to live-stream an employee Q&A session to the public on Thursday after recordings from a similar meeting in July were leaked and published earlier this week.

Zuckerberg addressed a range of topics and even waded into political views expressed by presidential candidates Bernie Sanders and Elizabeth Warren. He was also asked which types of fake news Facebook tries to prevent and how the San Francisco Bay Area's housing crisis is impacting the company.

Asked to respond to Sen. Sanders's comment that billionaires should not exist, Zuckerberg offered an unexpected viewpoint, considering his Facebook ownership makes him worth over $69 billion.

"I understand where he's coming from," Zuckerberg said. "I don't know that I have an exact threshold on what amount of money someone should have but on some level no one deserves to have that much money."

Sen. Warren has taken more of a direct attack on Facebook, claiming that the company should be broken up. The Verge on Tuesday published audio and transcripts from a Q&A session in which Zuckerberg blasted Warren's plan and said he'd "go to the mat" and fight it.

Zuckerberg said on Thursday that he stands by all the content in the leaked recording, but he added, "let's try not to antagonize her further."

In announcing the public session, Zuckerberg wrote in a post that he thought "it would be good to show everyone what these Q&As are like." He said that he thinks an intern leaked the contents of the prior Q&A because it was a session for interns.

He compared himself to a robot that needs recharging and joked during the live stream, "At this point, I do such a bad job at interviews that what do we have to lose?"
