Senate Minority Leader Chuck Schumer (D-N.Y.) has called for a federal investigation into FaceApp, saying the Russian-operated mobile application "could pose national security and privacy risks for millions of US citizens."

FaceApp for iOS and Android has been around since 2017 but just recently went viral as celebrities and many other people used it to alter photographs to make themselves look 20 years older. This has raised privacy concerns, as Americans are uploading photographs and device-related data to a service operated by a company based in Russia. The image alterations performed by FaceApp—which calls itself an "AI Face Editor"—are done on the company's servers instead of on user devices.
