Whatever he believes or doesn’t, he makes untrue assertions more frequently than any U.S. leader in recorded history. The fact-checking organization PolitiFact looked at four hundred of his factual statements as a candidate and as president and found that 50 percent were completely false and another 20 percent mostly false. After he became president, according to The Washington Post, he issued an average of more than four falsehoods or “misleading claims” per day.
