This man is DANGEROUS. He is a pathological LIAR. He is INDIFFERENT to the TRUTH, FACTS, EVIDENCE and PROOF. Those are the CORNERSTONES of JUSTICE. Those are the FIRST PRINCIPLES of SCIENCE. This is a glaring EXAMPLE of a NARCISSISTIC SELF-AGGRANDIZING EXAGGERATION. This is two blatant LIES in 18 seconds. The first LIE: "Nobody KNOWS the SYSTEM BETTER than me." That is a blatant LIE. There are many EXPERTS who KNOW the SYSTEM much BETTER than Donald Trump. Then he says, "Which is why I alone CAN fix it." That's NOT TRUE. Most likely he CANNOT fix it. There are others who CAN. That's two blatant LIES in 18 seconds.
