Facebook CEO Mark Zuckerberg appears before Senate committees

(KFVS/AP) - Facebook CEO Mark Zuckerberg appeared before Senate Judiciary and Commerce Committee on Tuesday, April 10.

The joint hearing comes after revelations that Cambridge Analytica, a data-mining firm affiliated with Donald Trump's presidential campaign, gathered personal information from 87 million users to try to influence elections.

Facebook started notifying users if their personal data and information was compromised by Cambridge Analytica on Tuesday morning, hours before Zuckerberg will testify in front of Congress.. Here's what you need to know about his testimony.

Zuckerberg visited with senators in closed-door meetings Monday, previewing the public apology he plans to give Congress on Tuesday.

But what could this mean for the social media site? We talked to users about where the future of snap chat is headed, most feel it's in a downward direction.

"Well, all my friends are shifting more towards Instagram," said Jaden Barnes, a SEMO Student.

"I mean as far as using [Facebook] as an entertaining social media thing that's only when I'm really bored," said Deshawn Smith. "Twitter most definitely will probably take over Facebook."

According to eMarketer, a research and data website, Facebook is still the largest social network but is losing the younger generation while Snapchat and Instagram are gaining.
