President Donald Trump said on Friday he is banning CNN, MS NOW and Politico from the White House.

He blamed their "fake news" and bad coverage of him.

He also said he may ban more media later.

Trump did not explain how the ban would work.

Later, in the Oval Office, Trump said the outlets were "fake news."

He said the country needs honest news.

CNN said it supports its White House team.

CNN said its reporting is fair and correct.

CNN said the ban is an illegal attack on a right protected by the Constitution.

Politico said it will keep reporting fairly.

Politico said it will defend its First Amendment rights.

MS NOW did not answer a request for comment right away.

This comes after Trump's decision last year.

He kept reporters out of the Oval Office and Air Force One.

That was to punish an outlet.

The outlet refused to use his new name for the Gulf of Mexico.

Reporters sued, and that case is still going on.

Trump has also taken legal action against The New York Times, The Wall Street Journal and the BBC.

Banning CNN could disrupt the traditional five-network TV pool.

That pool travels with the president.

A 1977 court ruling said the White House cannot deny press access because of coverage.

A federal judge ruled the government cannot punish reporters over editorial decisions.

But an appeals court paused most of that ruling.

The case is still pending.
