Mostly sarcastic, but there is a secret service rule that the president is not allowed to drive on public roads. The rest is all debatable because it hasn’t been litigated. They answer to the president, but a president can not refuse secret service protection.

Technically Walter Gerber and Fritz Stettler invented the first processed cheese in Switzerland in 1911 by heating cheese up and mixing in sodium citrate. Kraft patented the process in the USA in 1916. The term “American Cheese” was later coined to refer to any processed cheese.

The American Cheese Wikipedia page is poorly written with mostly redundant information from other Wikipedia pages… it’s just a commonly used word to refer to processed cheese and marketing term.
