WATCH: Sheryl Sandberg says Facebook has made progress on fighting election meddling

WASHINGTON — Facebook’s No. 2 executive has told a Senate committee that Facebook has made progress in addressing the issue of meddling by foreign interests in U.S. elections. But Sheryl Sandberg also says security efforts to combat such threats are never finished.

She tells the Senate intelligence committee that Facebook is “more determined” than adversaries seeking to interfere in American democracy. Sandberg says Facebook is working with outside experts, law enforcement and government, and she acknowledges that Facebook doesn’t always have the expertise to determine the source of such threats.

Sandberg says “we are more determined than our opponents and we will keep fighting.” She calls the fight an “arms race,” as Facebook CEO Mark Zuckerberg has in the past.
