WASHINGTON — The U.S. Department of Justice is looking into whether five of the nation’s largest broadcast outlets — ABC, CBS, CNN, NBC and Fox News — violated federal antitrust law when they temporarily dropped coverage of President Donald Trump last month.

The investigation was prompted after Trump’s administration revoked credentials for reporters at CNN, MS NOW and Politico, forcing the networks to exit the White House press pool for several days.

The DOJ has requested internal communications from the networks and is examining whether the coordinated boycott could breach the Sherman Act, which prohibits monopolistic or conspiratorial conduct that restricts competition.

The networks have so far refused to comment, but the dispute has already reached the courts. CNN, MS NOW and Politico sued the White House, arguing that the bans violated their First‑Amendment protections; a judge later reinstated access pending the validity of the lawsuits.

Besides the antitrust angle, the case will test the limits of executive power over media access, with the White House also moving to re‑take control of the press pool itself—a move that has drawn criticism from press‑rights advocates.
