Η Committee The Senate Chamber of Commerce has asked the CEOs of Google, Facebook and Twitter to testify on October 1.
It's an unusually tight schedule for such a high team Profile, but members have said they may issue penalties if CEOs do not agree to appear by the end of the day on Thursday.
It is also possible that other board members will oppose the calls or that the CEOs will find another way to avoid the calls, while Google, Facebook and Twitter did not immediately respond to requests for comment.
The hearing will reportedly focus on measures to amend Article 230, a basic law on content surveillance practices in the Internet. In July, a subcommittee hosted a hearing on the law PACT - an apparent compromise between the biased and the most measured reformers - although the results of the debate were unclear.
The Senate Commerce Committee, before summoning the CEOs of Google, Facebook, and Twitter, launched several investigations into alleged anti-conservative bias on Facebook and challenged him. Mark Zuckerberg, immediately after her scandal Cambridge Analytica. The most recent hearings on alleged anti-competitive behavior by technology companies have been handled by judicial committee committees, which preside over antitrust.
Possible changes to Article 230 have become a key issue for Congress as elections to the USA and more candidates violate the systems. Also Thursday, the senator Josh Hawley introduced a new bill that would impose sanctions on platforms if they are found not to function properly.
"It's time to take a fresh look at the statute and clarify the vague pattern of 'good faith' for which technology companies receive legal protection." said Senator Marco Rubio.
