"Trump’s willingness to constantly repeat false 
claims has posed a unique challenge to fact-checkers. Most politicians 
quickly drop a Four-Pinocchio claim, either out of a duty to be accurate
 or concern that spreading false information could be politically 
damaging.
Not Trump. The president keeps going 
long after the facts are clear, in what appears to be a deliberate 
effort to replace the truth with his own, far more favorable, version of
 it. He is not merely making gaffes or misstating things, he is 
purposely injecting false information into the national conversation.
To accurately reflect this phenomenon, The Washington Post Fact Checker is introducing a new category — the Bottomless Pinocchio.
 That dubious distinction will be awarded to politicians who repeat a 
false claim so many times that they are, in effect, engaging in 
campaigns of disinformation."
