MORE: Fox News backs CNN in lawsuit against Trump, wants Acosta reinstated.

In its complaint filed in U.S. District Court on Tuesday, CNN argued that the revocation of Acosta’s access was “the culmination of years of hostility by President Trump against CNN and Acosta” based on its reporting and “an unabashed attempt to censor the press and exclude reporters from the White House who challenge and dispute the President’s point of view.”

In response, the Justice Department argued in a court filing that Trump has “broad discretion to regulate access to the White House for journalists.”

Wallace said Fox News intended to file an amicus brief in support of CNN with the court ahead of an afternoon hearing.

Fox News is alienating its core audience in support of a deeply flawed lawsuit.

Dumb.
