Facebook has suspended Strategic Communication Laboratories (SCL) and its affiliate, data analysis and targeting firm Cambridge Analytica, for "violating our platform policies."

It has become a focus of both the House Intelligence Committee’s investigation into Russian election meddling and Robert Mueller’s probe.
