what crimes constitute treason
By Section 110 of Article III. of the Constitution of the United States, it is declared that: Treason against the United States shall consist only in levying war against them, or in adhering to their enemies, giving them aid and comfort. No person shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open Court. The Constitution confines the crime of treason to two species; First, the levying of war against the United States; and Secondly, adhering to their enemies, giving them aid and comfort.
