Although Facebook says Mr Zuckerberg has no plans to travel to the United Kingdom, we would also be open to taking his evidence by video link, if that would be the only way to do this during the period of our inquiry.
The 39 questions were given to Facebook after an initial meeting with Mike Schroepfer, chief technology officer for the firm, failed to address all of the committee's concerns.
United Kingdom committees can compel witnesses (other than the monarchy, government ministers, MPs and Lords members) within the United Kingdom to attend and answer questions, according to think tank The Institute for Government. Damian Collins, chair of the Digital, Culture, Media and Sport Committee, said in a statement: "It is disappointing that a company with the resources of Facebook chooses not to provide a sufficient level of detail and transparency on various points".
In the case of this new data scandal, the "myPersonality" quiz was used to collect various pieces of information about users who took part in a psychologyquiz on Facebook.
Facebook suspended the app on April 7, after it accessed the "Big Five" personality scores of 3.1 million users, and two million status updates from over 150,000 users, including details about age, gender and relationship status from 4.3 million people.
The investigation, which Archibong says is "in full swing", has covered thousands of apps so far (no word on how many apps Facebook has left to scrutinize). "We have large teams of internal and external experts working hard to investigate these apps as quickly as possible". They mentioned that the committee found Schroepfer's responses to questions lacking and asked Zuckerberg to appear or the Facebook CEO will face the consequences.
Wayne Rooney to DC United
On Friday, Everton boss Sam Allardyce said Rooney has not asked to leave . They did then, I don't know if they exist as much now". Next season is already planned.
Facebook has been embroiled in a number of data protection and privacy scandals in recent months, most notably surrounding the alleged election-interfering firmCambridge Analytica.
It added that "Cambridge Analytica is a data-driven marketing agency and does not manipulate political views". For those unaware, in 2014, Facebook had changed its policies to no longer allow developers accessibility to information of their app users' friends.
During his evidence session, Schroepfer said this was at the request of "people" in these countries, who wanted to work with a local regulator rather than Facebook Ireland.
Social-media companies have come under intense scrutiny over reports that Facebook failed to protect the privacy of is users.
With all that, deanonymizing the data would be a snap, Dixon said. However, this is yet another reminder that when you agree to sharing your data with one app, it is going to be mass circulated, ending up online. "We were disappointed after providing a very significant amount of information to the committee at the last hearing the committee declared our response insufficient", wrote Stimson.
