Investigation launched after five broadcasters last month ceased presidential coverage after CNN, MS Now and Politico were barred from White House

The US Department of Justice is investigating whether the decision of the White House television press pool to halt coverage of the US president, Donald Trump, last month violated antitrust law, an agency spokesperson said Saturday.

A spokesperson for the department said group boycotts among business competitors might violate US law. “The Antitrust Division is simply investigating to determine whether these news organizations have violated the antitrust laws,” they said.
