German media giant Bertelsmann's Penguin Random House, already the largest American publisher, wants to buy New York-based Simon & Schuster, whose authors include Stephen King, Hillary Clinton and John Irving, from TV and film company ViacomCBS.

The Department of Justice filed an antitrust suit in the U.S. District Court for the District of Columbia Tuesday in the first major antitrust action by the Biden administration, saying the deal would let Penguin Random House "exert outsized influence over which books are published in the United States and how much authors are paid for their work."

"If the world's largest book publisher is permitted to acquire one of its biggest rivals, it will have unprecedented control over this important industry. American authors and consumers will pay the price of this anticompetitive merger – lower advances for authors and ultimately fewer books and less variety for consumers," said Attorney General Merrick Garland in a statement.
