Facebook, Twitter CEOs facing questions on election measures

A Senate panel is calling on the CEOs of Facebook and Twitter to defend their handling of disinformation in the contest between President Donald Trump and Democrat Joe Biden. But the senators are deeply divided by party over the integrity and results of the election itself.

The Senate Judiciary Committee is holding a hearing Tuesday to question Facebook’s Mark Zuckerberg and Twitter’s Jack Dorsey on their companies’ actions around the closely contested election. The two social media CEOs are expected to testify via video.

Prominent Republican senators — including the Judiciary Committee chairman, Sen. Lindsey Graham of South Carolina — have refused to knock down Trump’s unfounded claims of voting irregularities and fraud, even as misinformation disputing Biden’s victory has flourished online.
