Facebook told British lawmakers on Thursday that it never read the terms and conditions for an app that ultimately allowed Cambridge Analytica to access 87 million users’ names, “likes” and other personal information.

The admission from Mark Schroepfer, the chief technology officer for the social media giant, concerns a quiz app made by researcher Alexander Kogan, and his firm known as GSR, which collected data on users who authorized it, as well as scores of their friends. It then transferred that data to Cambridge Analytica, a political consultancy that later had been hired by President Trump, so that the firm could assemble psychographic profiles of voters.
