The UK data regulator is investigating Facebook, along with 29 other companies, as it probes the use of data by political campaigns following the Cambridge Analytica scandal, and has warned it may take "enforcement action."
The Information Commissioner's Office (ICO) has been conducting an investigation into the political research firm used by Trump's presidential campaign/
It follows the revelation that it improperly obtained tens of millions of Facebook users' personal data.
The ICO is also conducting a broader investigation into "how social media platforms are used in political campaigning," and on Thursday it announced that it is investigating 30 companies as part of that - including Facebook.
The investigation could result in "enforcement action" being taken, the ICO said. It isn't yet clear whether the changes the social network has made in recent weeks to bolster user privacy are sufficient to comply with UK standards.
In a statement, Information Commissioner Elizabeth Denham said: "Facebook has been co-operating with us and, while I am pleased with the changes they are making, it is too early to say whether they are sufficient under the law.
"This is an important time for privacy rights. Transparency and accountability must be considered, otherwise it will be impossible to rebuild trust in the way that personal information is obtained, used and shared online.
"This is why, besides my investigation, which could result in enforcement action, I will also be making clear public policy recommendations to help us understand how our personal data is used online and what we can do to control how it's used."
On Tuesday, Facebook revealed that up to 87 million users' data had been obtained by Cambridge Analytica - far more than the previous estimate of 50 million circulating in the press. The social network also announced a series of changes designed to restrict outside parties' access to user data.
In a conference call with reporters, CEO Mark Zuckerberg insisted he was still the best person to lead the company following the privacy uproar and previous scandals over fake news and disinformation.
The ICO is currently in the process of investigating Cambridge Analytica, which is based in England, and raided its offices on March 23.
Here's the full statement from Information Commissioner Elizabeth Denham:
"As part of my investigation into the use of personal data and analytics by political campaigns, parties, social media companies and other commercial actors, the ICO is investigating 30 organisations, including Facebook.
"The ICO is looking at how data was collected from a third party app on Facebook and shared with Cambridge Analytica. We are also conducting a broader investigation into how social media platforms were used in political campaigning.
"Facebook has been co-operating with us and, while I am pleased with the changes they are making, it is too early to say whether they are sufficient under the law.
"This is an important time for privacy rights. Transparency and accountability must be considered, otherwise it will be impossible to rebuild trust in the way that personal information is obtained, used and shared online.
"This is why, besides my investigation, which could result in enforcement action, I will also be making clear public policy recommendations to help us understand how our personal data is used online and what we can do to control how it's used."
