"Donald Trump and his campaign have waged an aggressive campaign against fact-checking in recent months, pushing TV networks, journalism organizations and others to abandon the practice if they hope to interact with Trump...
The moves are the latest example of Trump’s long-held resistance to being called to account for his falsehoods, which have formed the bedrock of his political message for years. Just in recent weeks, for example, Trump has seized on fabricated tales of migrants eating pets and Venezuelan gangs overtaking cities in pushing his anti-immigration message as he seeks a second term in office.
Lucas Graves, a journalism and mass communications professor at the University of Wisconsin at Madison, said that publicly chafing at fact-checking has become a form of tribalism among some Republicans.
“Within the political establishment on the right, it is now considered quite legitimate — and quite legitimate to say publicly and openly — that you disapprove of fact-checking,” said Lucas, author of “Deciding What’s True: The Rise of Political Fact-Checking in American Journalism."
