Trump has had a fraught relationship with the media since the campaign trail. Throughout his campaign and presidency, Trump has derided the media as "fake news" and even blocked reporters from certain events.

During his rally in Indiana on Thursday, Trump railed against the news media, lambasting NBC and CNN, as well as a New York Times reporter, over coverage of his past crowd sizes, saying the reporter "doesn't have a clue."

"These are just dishonest, terrible people," he said.
