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.
