I beg to differ. The Sgt. Schultz defense is "I know Nothing!" The Constanza defense is "Remember, Jerry, it's not a lie if you really believe it."

[Edited to add] Trump uses the Constanza defense. It's the rest of the party that uses the Sgt. Schultz defense. They're like the three monkeys. "See no evil. Hear no evil. Speak no evil."
