Trial Begins in Justice Department’s Bid to Block Book Publishing Merger

WASHINGTON—Trial proceedings kicked off in the Justice Department’s antitrust challenge to Penguin Random House’s planned acquisition of rival publisher Simon & Schuster, a test for the Biden administration’s efforts to limit corporate consolidation.

“This proposed merger must be stopped,” Justice Department lawyer John Read said in his opening statement Monday. “It would, in the defendants’ own words, cement Penguin Random House’s dominance.”
