A spokeswoman for the House Energy and Commerce Committee said Tuesday that the committee is working with Facebook to determine a day and time for Zuckerberg to testify.
Meanwhile, Zuckerberg snubbed a summons from a British Parliamentary committee investigating the rise of fake news, offering to send senior Facebook executives instead.
This would be the first time Zuckerberg has ever testified before Congress. Last fall, the company sent its top lawyer to speak before Congress about Russian interference in the 2016 elections. Google and Twitter also sent lower-level executives to the three public hearings on the matter.
Separately, Facebook announced a privacy settings makeover on Wednesday. While the move is intended to prepare for tighter European privacy regulations going into effect in May, Facebook said that recent events "underscore their importance."
The changes won't affect Facebook's privacy policies or the types of data it gathers on users. But the company hopes its 2.2 billion users will have an easier time navigating its complex and often confusing privacy and security settings. Facebook says it also wants to give users a simpler way to access and download the data it collects on them.
Chris Cox, Facebook's chief product officer, called the new settings "the first of many steps" the company is taking to address privacy concerns.
