In what will be one of the largest battles yet between the press and Donald Trump’s administration, three news organizations – CNN, MS Now (formerly MSNBC) and Politico – that have been denied access to the White House are suing him on Monday to attempt to regain their ability to enter the building.

The suit will be filed Monday morning in the US district court for Washington DC.

Journalists for the three news organizations were denied access to the White House and had their badges disabled on Saturday after the president decried a day earlier that they would lose their ability to enter the building because of his concerns about their coverage.

“This morning, we notified the government that we are filing a lawsuit today to protect our First Amendment rights and defend the principle that the government does not decide what the press reports or publishes,” the news organizations said in a statement, referring to the US constitutional amendment guaranteeing a free press.

“Without notice or process, the White House revoked our journalists’ credentials because it objected to our reporting. Left unchallenged, this threatens press freedom and the public’s right to independent journalism free from government interference.”
