US Dept of Justice to probe ABC, CBS, CNN, Fox & NBC over Trump coverage halt. US Department of Justice will investigate ABC, CBS, CNN, Fox and NBC over their decision to halt coverage of President Trump. The TV networks stopped pooled presidential coverage last month after CNN, MS Now and Politico were barred from White House. The department will examine whether their coordinated suspension amounted to an unlawful “group boycott” under the Sherman Antitrust.
