Mark Zuckerberg, speaking at a fireside chat at the Munich Security Conference, said that since 2016, Facebook has "played a role in helping to defend the integrity of" more than 200 elections around the world.

Why it matters: On top of growing revenue and the number of users on Facebook, Zuckerberg also has to ensure that the platform is not blamed for negatively influencing elections and does not buckle on freedom of speech.

What he's saying: Zuckerberg said the successful techniques have included "developing AI systems that can identify fake accounts and networks of accounts."

  • "In the last couple of weeks, we took down one that was coming out of Russia [targeting] Ukraine, and one coming out of Iran that was targeting the U.S."
  • Zuckerberg said the majority of the more than 1 million fake accounts Facebook takes down each day aren't connected to state actors interfering with elections. They're spammers.
  • "One of the things that we are tracking that we have been quite worried about is that increasingly, election interference ... is ... also domestic. You have ... local actors also trying to employ some of the same tactics. ... We have also seen these actors get more sophisticated at trying to hide their tracks."

Zuckerberg said a big Facebook transformation in the last few years has been "from being more reactive about addressing content-type issues to being more proactive":

  • "I started the company in my dorm room. Back then, we could not have 35,000 people doing content and security review. The AI. 16 years ago, did not exist ... to identify this type of harmful stuff."

"Hate speech is a particularly challenging one," he continued. "We have to be able to train AI systems to detect ... nuances. Is someone posting a video of a racist attack because they are condemning it ... or are they encouraging other people."

  • "Multiply ... that subtlety, linguistically, by 150 languages around the world where we operate."

Blizzard warnings are in effect for 11 million people from coastal Virginia to eastern Maine as a powerful and potentially historic winter storm is set to slam the Mid-Atlantic and Northeast beginning Friday.

Why it matters: The storm will bring an array of hazards, from zero visibility amid hurricane force wind gusts and heavy snow to coastal flooding that will erode vulnerable beaches and threaten coastal property from the Jersey shore to coastal Massachusetts.

A Republican-led Pennsylvania court on Friday ruled that the state's mail-in voting law is unconstitutional.

Driving the news: Three Republican judges sided with Republican challengers and ruled that no-excuse mail-in voting is prohibited under the state's constitution. Two Democrats on the panel dissented.

China's ambassador to the U.S. warned in a rare interview with NPR that if Taiwanese authorities "keep going down the road for independence," it would "most likely" lead to a "military conflict" between the U.S. and China.

Why it matters: Chinese officials rarely speak in such blunt terms, but veteran diplomat Qin Gang was unequivocal: "The Taiwan issue is the biggest tinderbox between China and the United States."
