President Trump reportedly lashed out at aides after seeing first lady Melania Trump's television broadcasting CNN on Air Force One.

An internal email obtained by The New York Times said that the president caused "a bit of a stir" on the aircraft because the television was tuned in to the network he continuously blasts as "fake news."

Officials said in the email that they would turn the televisions to Fox News for future flights, according to the Times.

It is well-known that Trump's network of choice is Fox News, and he has repeatedly praised their coverage while disparaging other networks, in particular CNN.

At a joint press conference earlier this month with British Prime Minister Theresa May, Trump refused to take a question from CNN White House correspondent Jim Acosta, instead moving on to Fox News's John Roberts.

"CNN is fake news. I don't take questions from CNN," Trump said. "Let's go to a real network."

Earlier Tuesday, while speaking at the Veterans of Foreign Wars national conference, Trump attacked the press as "fake news" and told audience members not to believe what they see and read in the media about the economy.

"Just remember: What you're seeing and what you're reading is not what's happening," he said. "Don't believe the crap you see from these people, the fake news."

A memo circulated on social media earlier this year claiming that the Food and Drug Administration was ordered to display Fox News on all televisions in one of its units, which the FDA denied.
