WASHINGTON (AP) — The head of the House Intelligence Committee says he has been assured by the CEO of Facebook that company is working on ways to prevent foreign actors from disrupting next year's elections.

Rep. Adam Schiff of California met Friday with Mark Zuckerberg and said the Facebook CEO showed a deep awareness of the threat to the elections from so-called "deep fake" videos and other technically advanced tools.

Schiff told reporters Facebook is "in the process of developing what I hope will be very strong policies on this."

It was Zuckerberg's third day of private meetings in Washington, following other sessions with top lawmakers and President Donald Trump. Zuckerberg also met Friday with the leader of a House antitrust investigation into the big tech companies and pledged to cooperate.
