British data analytics firm Cambridge Analytica is at the center of controversy in the United States and Britain after two newspapers reported on Sunday that the company harvested personal data about Facebook users beginning in 2014.

Best known for assisting the 2016 presidential campaign of U.S. President Donald Trump, Cambridge Analytica is now facing a government search of its London office, questions from U.S. state authorities, and a demand by Facebook that it submit to a forensic audit.
