New York Times: Sources: the US DOJ is probing whether ABC, CBS, CNN, NBC, and Fox News violated antitrust law by briefly suspending their White House pool coverage of Trump — Major TV networks were notified on Friday that the department was looking into whether they violated antitrust laws when they suspended pool coverage of President Trump.



“Probe” is not used by the DOJ, this is a journalistic term. Probably used because it’s shorter and zippier.
