During an ill-judged cleaning operation, much of the patina was literally scraped away with wire brushes, copper chisels and coarse carborundum, also known as silicon carbide, a harsh abrasive cleaning agent that was deemed inappropriate even back then.

Along the way, try to remember what your fellow Floridian, Gen. Joe Stillwell, who led the fight against Imperial Japan in China, Burma and India, adopted as his Latin motto: “Illegitimi non carborundum.”

On Tuesday McCain cast further shade against the president by tweeting, "As my father always used to say to me - Illegitimi non carborundum."

Later in the night, Meghan McCain responded to Trump’s most recent attacks by tweeting, “As my father always used to say to me - Illegitimi non carborundum,” which means “Don’t let the b--tards grind you down.”

As my father always used to say to me - Illegitimi non carborundum.
