Treason against the United States is defined exclusively as levying war against the country or aiding its enemies. Conviction requires testimony from two witnesses to the same overt act or a confession in open court. The section also grants Congress the authority to determine the punishment for treason but prohibits corruption of blood or forfeiture beyond the life of the person convicted.
Under this statute, any person who owes allegiance to the United States and either levies war against the country or adheres to its enemies by providing aid and comfort is guilty of treason. The punishment for treason can be death or imprisonment for no less than five years and a fine of at least $10,000. Additionally, individuals convicted of treason are barred from holding any office under the United States.
