CNN, MS NOW, Politico notify Trump administration of lawsuit over White House access
In short:
CNN, MS NOW and Politico say they have notified Donald Trump's administration that they are filing a lawsuit after being denied White House access.
It comes after reporters from the three major news outlets were blocked from the White House over reporting Mr Trump called "fake news".
The move marks the latest escalation in the president's campaign to punish news media for coverage he finds objectionable.
