NEW YORK (AP) — The Latest on the alleged use of Facebook data to influence the U.S. presidential election (all times local):

3:50 p.m.

Facebook CEO Mark Zuckerberg is admitting mistakes and outlining steps to protect user data in light of privacy scandal involving a Trump-connected data-mining firm.

Zuckerberg is breaking more than four days of silence as he posts an update about the Cambridge Analytica scandal.

Zuckerberg posted on his Facebook page Wednesday that Facebook has a “responsibility” to protect its users’ data, and “if we can’t then we don’t deserve to serve you.”

Zuckerberg and Facebook’s No. 2 executive, Sheryl Sandberg, have been quiet since news broke Friday that Cambridge may have used data improperly obtained from roughly 50 million Facebook users to try to sway elections.
