From the U.S. Constitution:
Article III Section 3.
Treason against the United States, shall consist only of levying war against them, or in adhering to their Enemies, giving them Aid and Comfort. [snip]
If convicted of Treason, the sentence proscribed is death.
If Benjamin is quoted accurately, then I 'm the second witness that's required.
