Facebook CEO Mark Zuckerberg and Twitter CEO Jack Dorsey will voluntarily testify before the Senate Judiciary Committee next month to address allegations of bias in their handling of news coverage during the 2020 election cycle, committee Chairman Sen. Lindsey Graham announced Friday.

“The hearing will focus on the platforms’ censorship and suppression of New York Post articles and provide a valuable opportunity to review the companies’ handling of the 2020 election,” Graham, R-S.C., said in a statement.

The hearing will take place on Tuesday, Nov. 17, the committee said in a press release. 

Dorsey will testify virtually, a Twitter spokesperson confirmed, but did not comment otherwise. A Facebook spokesperson confirmed Zuckerberg would testify.

Facebook and Twitter faced widespread criticism earlier this month after each social media platform took steps to slow the spread of the New York Post’s report on emails taken a laptop that purportedly belonged to Hunter Biden. The emails detailed Biden’s alleged overseas business dealings with contacts in China and Ukraine.

A Facebook representative said the company would limit the spread of the article until its claims could be fact-checked. Twitter blocked the article from being shared entirely, in a step it said was due to its "Hacked Materials Policy." Twitter also locked the New York Post’s account and others that attempted to share the report until their posts were deleted.

Dorsey later acknowledged that Twitter had mishandled the situation, calling the decision to block the article without providing clear context as to why the action was taken “unacceptable.”

Leading Republicans slammed both companies for their handling of the situation and called on them to clarify their policies.

Earlier this week, Republican members of the Senate Judiciary Committee warned that Zuckerberg and Dorsey would be subpoenaed if they did not agree to voluntarily testify. Aside from a more detailed explanation of their handling of the New York Post report, the committee asked the tech executives to clarify their policies for moderating content “that may interfere” with federal elections.
