Before Wylie's testimony, committee members called out Facebook CEO Mark Zuckerberg, insisting he should be questioned over how millions of users' details got into the hands of political consultancy Cambridge Analytica, after the company said it would send another executive to appear before them.
Cambridge Analytica said on Tuesday that it had not shared any of the Facebook profile data procured by a Cambridge academic with AggregateIQ.
When asked about Cambridge Analytica's operations in India, the largest democracy with the largest number of Facebook users, Wylie, while not hesitant to name Congress, did not remember which elections it had helped out with.
"These issues must be addressed at the most senior levels of the company by those in an authoritative position", wrote Rebecca Stimson, head of public policy, Facebook UK.
"As such Mr Zuckerberg has personally asked one of his deputies to make themselves available to give evidence in person to the Committee".
The scandal is likely to affect the business of Facebook a lot.
"Today the whistleblower Christopher Wylie has confirmed that Cambridge Analytica worked with Congress". However, concerns about the privacy of those websites' users were raised in recent years, especially with the many incidents of private information leaks from Facebook and other websites.

Christopher Wylie, the whistleblower behind the Facebook and Cambridge Analytica scandal, said Tuesday that the election of Donald Trump as USA president in 2016 made him speak out about the practices being employed by the political data firm.
"They are an example of what modern-day colonialism looks like", Wylie testified. Wylie suggested that often such data companies are used to circumvent election expenditure declaration as most of these services are either deeply devalued or considered "free". Canada, Germany and the United States have all conducted and published the results from opinion polls that stated the public no longer trusts Facebook even after the social media platform ran ads apologising to the people of Britain and the US.
