On Tuesday, President Biden appointed Lina Khan to chair the Federal Trade Commission. She’s 32 and a law professor at Columbia University. She’s also an anti-trust icon who’s done a lot of research on the monopolistic practices of big tech companies. Khan’s appointment signals that the Biden administration is serious about reining in big tech.
