NBC News and Reuters reported late Oct. 1 that the US Senate Commerce Committee plan to hold a hearing on reforming Section 230, before the November 3 election if possible, and that they will subpoena Twitter’s Jack Dorsey, Facebook’s Mark Zuckerberg, and Alphabet-Google’s CEO Sundar Pichai. Sundar has in the past called moderation (as allowed by 230) a “hard computer science problem”.
Maria Cantwell (D-WA) heads the committee and was at first reluctant to try to do this before the election.
Republicans are going to be concerned about suppression of conservative speech, and Democrats are going to remain concerned about radicalization. Both parties will be concerned about how foreign actors seem to be able to stir up cognitively naïve Internet users.
NBC reports the story as from Reuters, yet I could not find the original on the Reuters website.
