WASHINGTON—The chief executives of Facebook Inc. and Twitter Inc. told lawmakers they did better in fending off election interference in 2020, while acknowledging mistakes and signaling an openness to more regulation.
The tough tone of questions from both parties at a congressional hearing Tuesday suggested that social-media giants face higher risks of new regulation in the next Congress that begins in January.
At the Senate Judiciary Committee hearing conducted over more than four hours by videostream, Facebook’s Mark Zuckerberg and Twitter’s Jack Dorsey touted improvements their companies made in blocking or reducing misleading information in the 2020 election. That led to less interference, the CEOs said. By contrast, the 2016 election was marred by meddling from Russia aimed at helping elect Donald Trump.
“I am proud of the work we have done over the past four years to prevent election interference and support our democracy,” Mr. Zuckerberg said in his opening statement. “Millions of Americans used our service to talk about the campaigns, access credible information about voting and register to vote.”
The pitch didn’t appear to persuade lawmakers, who renewed concerns about the platforms’ power and reach as well as their handling of specific election-related content.
