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.
