Trump says he's banning MS NOW, CNN and Politico from White House

President Donald Trump said Friday that he is banning MS NOW, CNN and Politico from the White House over their coverage of him.

Trump, who frequently accuses mainstream media outlets of writing "fake news," said in a Truth Social post that those outlets "shouldn't be able to constantly write or report FICTION and LIES."

He did not identify any specific coverage.

"Other Fake News Media Outlets to follow," Trump added.

The White House did not immediately respond to CNBC's request for comment on the post.

CNBC has reached out for comment from the three media outlets Trump targeted.

Trump's latest attempt to block access to disfavored news outlets could draw a legal challenge over violations of the First Amendment, which protects the freedom of the press.
