From: https://www.law.cornell.edu/constitution-conan/article-2/section-4/impeachment

“The impeachment provisions of the Constitution were derived from English practice, but there are important differences. In England, impeachment had a far broader scope. While impeachment was a device to remove from office one who abused his office or misbehaved but who was protected by the Crown, it could be used against anyone—office holder or not—and was penal in nature, with possible penalties of fines, imprisonment, or even death. By contrast, the American impeachment process is remedial, not penal: it is limited to office holders, and judgments are limited to no more than removal from office and disqualification to hold future office.”

Ok so in America ‘only for office holders’ but in England ‘ it could be used against anyone’

You see where I’m going with this? Verrry interesting

Make of that what you will
