The head of Trump-affiliated data-mining firm Cambridge Analytica has been suspended, while government authorities are bearing down on both the firm and Facebook over allegations the firm stole data from 50 million Facebook users to manipulate elections.
Facebook also drew continued criticism for its alleged inaction to protect users' privacy. Earlier Tuesday, the chairman of the U.K. parliamentary media committee, Damian Collins, said his group has repeatedly asked Facebook how it uses data. He said Facebook officials "have been misleading to the committee."
The committee summoned Facebook CEO Mark Zuckerberg to testify.
"It is now time to hear from a senior Facebook executive with the sufficient authority to give an accurate account of this catastrophic failure of process," Collins wrote Zuckerberg. "Given your commitment at the start of the New Year to 'fixing' Facebook, I hope that this representative will be you."
