The 2016 election exposed how social media could be used by a foreign adversary to sow dissent and distrust within American borders. In 2020, the fight against those threats rages on, and the number of players has expanded, abroad and domestically.
"One thing that gets lost is disinformation and online media manipulation in 2020 does not look the way it looked in 2008 and even 2016," said Zarine Kharazian, an assistant editor at the Atlantic Council's Digital Forensics Lab. "And what we've actually seen is detection has gotten a lot better."
