A group of Democratic lawmakers led by Sen. Elizabeth Warren raise antitrust concerns about Fox Corp.’s proposed acquisition of Roku Inc., calling on the Justice Department for an “impartial” review. The lawmakers sent a letter to U.S. Associate Attorney General Stanley Woodward urging scrutiny of the deal, which is valued at about $22 billion. In their message, they argue that combining Fox and Roku could eliminate a significant competitor in the free streaming market, potentially reducing consumer choice and allowing the merged company to gain market power. The Hollywood Reporter also reports that the letter expresses concern about what it characterizes as “recent rubber-stamping of deals,” suggesting the government may not be enforcing antitrust laws rigorously enough. Bloomberg reports the same letter and notes that the lawmakers are urging the DOJ to conduct a more independent assessment rather than treating the transaction as routine. Overall, the sources agree that the lawmakers are asking for heightened antitrust evaluation of the Fox-Roku transaction, citing potential effects on competition and enforcement practices.
