It seems the CEO isn't too anxious about the Committee's "invitation", though.
A British parliamentary committee has claimed that Facebook has failed to fully answer 39 questions relating to fake news and data privacy, Reuters reports.
But committee chairman Damian Collins said Facebook failed to provide "a sufficient level of detail and transparency" and complained of discrepancies between Mr Schroepfer's testimony and answers provided by Mr Zuckerberg to the US Senate.
As part of its inquiry, the committee has been investigating allegations of the improper use of data for 87 million Facebook users by Cambridge Analytica, which was hired by President Donald Trump's 2016 USA election campaign.
The company also said the apps would be subject to a more thorough investigation into how they handle user data.
In 2014, Facebook revealed a policy change restricting access to client information, however, noticed that a few applications still had the information it had acquired before the modification. It added that it had taken action against 370,000 apps in 2017.
Sadr eyes Govt as poll upset rocks Iraq
Abadi - who came to power in 2014 as IS rampaged across Iraq - has balanced off the U.S. and Iran during his time at the helm. The Iranian-backed Shi'ite militia chief Hadi al-Amiri came in second with about 1.2 million votes and will control 47 seats.
It's not easy to say goodbye, says Wenger

Opposition wants Nawaz to apologize over Mumbai attack remarks
Efforts by Pakistan to put on trial those India says are responsible for the Mumbai attack have stalled, while Saeed operates largely freely in Pakistan.
Looks like Facebook data leak issues are not buried once and for all.
A Cambridge Analytica said the company used Twitter for but insisted that it had never "undertaken a project with GSR focusing on Twitter data and Cambridge Analytica has never received Twitter data from GSR".
But it's also worth noting the way the MPs phrased some of these questions allowed Facebook this wiggle room - and opened up the avenue for debate on what a "real" answer would be. It is interesting then to note then that Apple is quietly beginning to enforce long-standing and long-ignored rules in the Apple iOS developer's agreement and App Store Review Guidelines that, except for two limited exceptions, precluded an app publisher from sharing information collected from users on their phones with third parties.
UK Parliament roars: Oi!
The document revealed that political consultancy AggregateIQ spent around 1.6 million U.S. dollars (£1.2 million) on adverts from the Vote Leave Facebook page during the 2016 European Union referendum campaign, as well as 329,000 dollars (£242,000) for BeLeave, 51,500 dollars (£37,900) for Veterans for Britain and 32,700 dollars (£24,100) for the DUP Vote to Leave.
Schroepfer's responses weren't enough to satisfy Parliament, though.
Large datasets are particularly useful for building a pattern of public opinion or receptiveness to certain topics and ideas, although Twitter bans companies from using the data to derive sensitive political information or matching it with personal information obtained elsewhere, it said.
