The White House’s decision to bar three major news outlets from its grounds has moved to the courts, after CNN, MS NOW and Politico sued, alleging their reporters’ credentials were revoked because of their coverage.

President Donald Trump announced the ban on September 18, accusing the outlets of “fake news.” Reporters Betsy Klein of CNN and Akayla Gardner of MS NOW were then turned away with deactivated badges, while Politico said its White House reporter Cheyenne Haslett was denied entry and had her badge confiscated.

The outlets filed a First Amendment lawsuit on September 21. Federal Judge Timothy Kelly, appointed by Trump in 2017, issued a 14-day restraining order on September 24, finding the revocations likely violated due-process rights and questioning the Justice Department’s national-security justification. The White House reinstated the badges the same day.

The fight is not over: Trump later barred CNN from Air Force One for a weekend trip, and television networks briefly suspended pool coverage in solidarity. The case is shaping into a major test of press freedom ahead of the midterm elections.
