Facebook is under fire after reports detailing how Cambridge Analytica, which worked with US President Donald Trump on the campaign, acquired and used Facebook's customer information. On Tuesday, US media reported that the Federal Trade Commission, a US regulator, is looking into Facebook's handling of personal data.
The company is accused of failing to properly inform users that their profile information may have been obtained and kept by Cambridge Analytica, a political consulting firm. The questions follow allegations that 50 million Facebook users' private information was misused by a political consultancy firm.
On Friday, Facebook suspended the consulting firm, saying it had acquired data from a researcher who violated the firm's policies. Facebook has said it is expecting questions but has not been told it is under investigation.
Cambridge Analytica "strongly denies" the allegations levelled against it. "We remain strongly committed to protecting people's information," Facebook deputy chief privacy officer Rob Sherman said. "We appreciate the opportunity to answer questions the FTC may have."

The agreement involved monitoring the issue for 20 years, and raises the potential for significant fines in the event of violations.
