The Reporters and Editors at Rupert Murdoch’s New York Post have been instructed not to use not to use reporting from CNN, MSNBC, The Times and The Washington Post as the sole basis for any Post article.

Trump has falsely labeled these (and other outlets) “fake news.”

The order was handed down by Michelle Gotthelf, the editor in chief of nypost.com

The NY Times writes that it is common practice at The New York Post and its website, nypost.com, to publish articles based entirely on other news outlets’ reporting, without independent confirmation by a Post journalist.

The ban on articles based on the work of CNN, MSNBC, The Times and The Washington Post was ordered days after a mob incited by the president stormed the Capitol building. The news media was a secondary target of the anti-government agitators. Amid the violence, Trump loyalists chanted, “CNN sucks,” and MSNBC journalists said they had made sure not to display MSNBC-identifying markers on their gear or clothing.

The Post did not comment on the order.
