On Monday, the US senator Ron Wyden sent Zuckerberg a detailed list of questions related to the breach, with a demand for answers by 13 April. Two members of the Senate judiciary committee, Democrat Amy Klobuchar and Republican John Kennedy, called for hearings with the CEOs of Facebook, Twitter and Google.
“It’s time for Mark Zuckerberg to stop hiding behind his Facebook page,” said the Conservative MP Damian Collins, chair of the digital, culture, media and sport select committee.
Referencing the government’s request for Facebook’s auditors to leave Cambridge Analytica’s offices, Collins tweeted: “These investigations need to be undertaken by the proper authorities.”
The three social media companies testified in Washington last fall, following the revelation that their platforms had been used by foreign agents seeking to illegally influence the US presidential election. All three companies sent their general counsels, a move that was criticized at the time. It is unlikely that Zuckerberg will be able to avoid congressional questioning a second time.
