“After committee staff received a briefing yesterday from Facebook officials, we felt that many questions were left unanswered,” Walden and Pallone said in a joint statement.

“Mr. Zuckerberg has stated that he would be willing to testify if he is the right person. We believe, as CEO of Facebook, he is the right witness to provide answers to the American people,” they said.

They said in the statement that a formal letter will be sent to Zuckerberg "in the coming days."

Zuckerberg said during a media blitz on Wednesday night that he is open to testifying before Congress, but only if he is the correct person at Facebook to do so.

Facebook's data practices are under intense scrutiny after it was revealed that Cambridge Analytica took data from 50 million of Facebook users without their permission and then did not delete data after telling Facebook it would.
