British lawmakers called on Facebook CEO Mark Zuckerberg Tuesday to give evidence related to the company's links to political analysis firm Cambridge Analytica.

Media reports published by the U.K. newspaper The Observer and The New York Times on the weekend outlined how 50 million Facebook profiles were mined for data by an app called "thisisyourdigitallife". The data was then transferred to Cambridge Analytica.
