CNN has threatened further legal action if its journalists continue to be denied access to Air Force One. The network has been in a legal battle with Donald Trump’s administration since the president banned it and two other outlets from White House grounds, calling their content “Fake News.” Last week, a federal judge granted a preliminary injunction against the ban. However, CNN remains barred from TV pool coverage of Trump’s travel on Air Force One. CNN attorney Theodore J. Boutrous Jr. wrote a letter Monday to the Justice Department threatening additional legal action. The department did not respond to a request for comment.

CNN, MS NOW and Politico say they’ve notified President Donald Trump's administration that they’re filing a lawsuit over being denied White House access. Reporters from the three major news organizations were blocked from the White House on Saturday, a day after Trump said he was barring them because of reporting he found to be “fake news.” The actions were a clear escalation of Trump’s long-running efforts in the courts and through administrative action to restrict news coverage by journalists he finds objectionable and were the latest test of First Amendment protections in the United States. Trump had said Friday he would ban all three outlets because of coverage he disliked.
