Facebook says 87 million people may have been affected by the Cambridge Analytica scandal, a significantly higher number than the 50 million described in earlier news reports from The Guardian and New York Times.

“We didn’t take a broad enough view of what our responsibility is and that was a huge mistake."

Asked by a reporter on the conference call if he thinks he’s still the best person to lead Facebook, Zuckerberg replied: “Yes … I think life is about learning from the mistakes and figuring out what you need to do to move forward … What people should hold us accountable for is learning from the mistakes.”

What they're doing about it: The company is announcing nine changes to how it shares data in response to the data improperly shared with Cambridge Analytica. Earlier today the company updated its terms of service for first time since 2015.

Stay tuned: Zuckerberg is heading to Capitol Hill next week. He'll testify before the House Energy and Commerce Committee on April 11th.

A new Elvis TV documentary is coming later this month on HBO, the A.P.'s Kristin M. Hall reports:

• “'Elvis Presley: The Searcher,' a two-part, three-hour documentary, will premiere April 14 on HBO."
• "Director Thom Zimny, who worked on several Bruce Springsteen documentaries, had full access to Graceland’s vault and made ample use of it to unearth little-seen footage."
• "Along with his family and friends, Zimny interviewed studio musicians, producers, engineers and directors, as well as artists like Springsteen, Tom Petty and Emmylou Harris. Zimny uses only voiceovers for the narration instead of seeing the interviewees’ faces to keep the focus on the music and footage of Elvis over his career."
