Republicans on the US House Judiciary Committee would like Twitter CEO Jack Dorsey to join other chief executives of major tech firms at the hearing next week, Representative Jim Jordan, a Republican, wrote in a letter.
"We believe there is bipartisan interest to hear from Twitter about its power in the marketplace, its role in moderating content on its platform, and the causes for its recent highly publicized security breaches", Jordan wrote.
The hearing in question is expected to take place on 27 July when Apple's Tim Cook, Amazon's Jeff Bezos, Google's Sundar Pichai and Facebook's Mark Zuckerberg will appear before the House Judiciary Antitrust Subcommittee.
According to House Judiciary Committee Chairman Jerrold Nadler and Antitrust Subcommittee Chairman David Cicilline, their testimony would be essential to complete their investigation into competition in the digital marketplace.
The calls for Jack Dorsey to testify come as Twitter experienced a massive hack mid-July. The hack saw Barack Obama, Joe Biden, Elon Musk and other well-known US figures lose access to their accounts. The hackers then posted messages urging users to send bitcoin to an account to receive double the amount back.
