Of the late, Trump has expanded his war on truth to those who do the work of fact-checking him
TRUMP: I get my numbers from a lot of sources, like Homeland Security in particular, and the numbers that I have from Homeland Security are a disaster. numbers that come out of Homeland Security, Kirstjen (Nielsen), for the cost that we spend and the money that we lose because of illegal immigration, billions and billions of dollars a month.  ACOSTA: So your own government's stats are wrong, are you saying?
TRUMP: No, no, I use many stats. TRUMP: Let me tell you , you have stats that are far worse than those I use, but I use many stats, but I also use Homeland Security.
"Many stats." Which stats?
It's important to take a step back here to see what's happening: The President of the United States, one of the most powerful people in the county and the world, is not only completely unconcerned with telling truth, but is also actively working to discredit those who try to keep the capital "T" in truth
He is aggressively eroding the idea of fact and truth for a simple reason: Because he pursues his own political interests. Trump ran as the "anti-elites" candidate, casting himself as someone not bound by the political correctness and liberalism that Democrats, the media and even many Republicans had fired over the average person over the past decades. Somehow, the notion of "facts" and "truth" became elitist in Trump's hands: These fact-checkers work for mainstream media. The mainstream media is liberal and biased. Ergo, their "truth" can not be trusted
It worked. And as his campaign against facts has been successful, Trump has grown more and more brazen about it.
So, yeah. That's where we are: A president at war with the truth and the idea of objective facts. And a cohort of his supporters who believe that Trump's truth is the only one that matters and revels in the consternation their unwillingness to acknowledge that facts exist causes
This will be one of Trump's lasting legacies. More than the travel ban. More than the wall. More than all of the bullying tweets. More than his alleged war with the "deep state." The attempted elimination of truth and fact has – and will continue to – have a devastating effect not only on politics but on the broader culture. If we can not agree on a basic set of facts, how can we even talk to each other – much less find ways to compromise
Remember: Facts are not a party
