Justice Department and FBI Are Investigating Cambridge Analytica

The Justice Department and the FBI are investigating Cambridge Analytica, the now-defunct political data firm, and have sought to question former employees and banks that handled its business. Prosecutors have questioned potential witnesses in recent weeks, telling them that there is an open investigation into Cambridge Analytica — which worked on President Trump’s election and other Republican campaigns in 2016 — and “associated U.S. persons.” But the prosecutors provided few other details, and the inquiry appears to be in its early stages, with investigators seeking an overview of the company and its business practices. The investigation appears to focus on the company’s financial dealings — investigators have reached out to the company’s banks, for instance — and how it acquired and used personal data pulled from Facebook and other sources. In a sign of the inquiry’s scope, one of the prosecutors involved is the assistant chief of the Justice Department’s securities and financial fraud division, Brian Kidd. The effort is being assisted by at least one agent who investigates cybercrime for the FBI.
