Twitter, Facebook CEOs defend election actions, promise more

WASHINGTON: The CEOs of Twitter and Facebook on Tuesday defended their safeguards against disinformation in the presidential election, and promised Congress they would take vigorous action for two special elections in Georgia that could determine which party controls the U.S. Senate.

Twitter CEO Jack Dorsey and Facebook CEO Mark Zuckerberg told a hearing of the Senate Judiciary Committee they have strong programs in place to protect their platforms from being used to disseminate falsehoods or discourage people from voting in the Georgia elections.
