One Donald J. Trump himself. Unbeknownst to many, Trump has secretly purchased all rights to the term, "idiot"*, just as he tried to do with the phrase, "You're Fired", back in 2004. As a matter of fact, you now owe Mr. President Trump residuals for your unlicensed use of his newly (and legally) acquired property in your rubric. Please make proper payment to the estate of one Mister President Donald J. Trump or face litigation.
*The above and subsequent uses of the term "idiot" are used with the sole permission and behest of one (President) Donald J. Trump.
