What is the only crime defined in the US Constitution?
From the web: Treason is the only crime that has its minimum standard set in the Constitution itself, in Article 3, Section 3. There, treason is defined and the standard for conviction is set. No other crime is treated so thoroughly. However, Article 1, Section 8, Clause 6 specifically mentions counterfeiting, which may be what your friend is thinking of. Other clauses in that section mention much more nebulous crimes, such as “Piracies and Felonies committed on the high Seas” and the like.
