The United States Constitution defines treason as levying war against the country or giving aid and comfort to its enemies. It also specifies that no person shall be convicted of treason unless there is testimony from two witnesses to the same overt act or a confession in open court. The Framers of the Constitution recognised the distinction between traitorous actions and treasonous thoughts, requiring an act of betrayal before a person could be convicted of treason. The Constitution further states that Congress has the power to declare the punishment for treason, and that the punishment of treason ends with the death of the traitor.

Treason is defined as levying war against the US or providing aid to enemies
The US Constitution defines treason as "levying war" against the United States or providing "aid and comfort" to its enemies. This definition is outlined in Article III, Section 3 of the Constitution, which is also known as the Treason Clause.
Levying war against the United States means more than just conspiring against the nation. It refers to an open action against the country through the use of force. In other words, it involves the actual waging of war. In Ex parte Bollman (1807), Chief Justice John Marshall emphasised that there must be an actual assemblage of men, for the treasonable purpose, to constitute a levying of war. This means that there must be an organised group of people assembled with the explicit purpose of using force to achieve a treasonable aim.
Providing aid to enemies of the United States means more than giving assistance that is casually useful to them. It involves offering support that is essential to an enemy's treasonous design. For example, in Cramer v. United States (1945), the Court held that certain acts could be considered "aid and comfort" if they aided in steps essential to the enemy's treasonous plan.
The Treason Clause also sets specific requirements for conviction. It states that no person shall be convicted of treason unless there is testimony from two witnesses to the same overt act, or a confession in open court. This clause protects against false or flimsy prosecutions.

The Constitution specifies the conditions for treason conviction
The US Constitution defines treason and outlines the requirements for treason convictions in Article III, Section 3. Treason is defined as levying war against the United States or providing aid to its enemies. The Constitution specifies 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".
The Constitution sets specific requirements for treason convictions. It states that no person shall be convicted of treason unless there is testimony from two witnesses to the same overt act or a confession in open court. This means that the federal government cannot secure a conviction for treason unless two witnesses testify about the same treasonous act, or the accused confesses in court. The "overt act" must also be "openly manifest treason" and not merely supported by circumstantial evidence.
The Supreme Court has clarified what constitutes "levying war" and providing "aid and comfort" to enemies. In the case of Ex parte Bollman (1807), the Court held that "levying war" requires an actual assemblage of men for the purpose of executing a treasonable design. Chief Justice John Marshall emphasised that there must be an actual assembling of men with the treasonable purpose to constitute a levying of war. This interpretation arose in the context of the treason trials of Aaron Burr and his associates, who conspired to overthrow the American government in New Orleans.
The Constitution grants the Supreme Court the power to interpret the law and administer justice, as well as the authority to declare acts of other branches unconstitutional. The Court has emphasised that treason is not the only legal weapon to protect national security, and federal prosecutors can pursue non-treason charges without needing to satisfy the procedural requirements of the Treason Clause.

The Treason Clause guards against false prosecutions
The Treason Clause, as outlined in the US Constitution, plays a crucial role in safeguarding against false or unfounded prosecutions for treason. This clause is not merely about underscoring the gravity of betraying one's nation but serves a more specific and protective purpose.
Historically, repressive governments have abused treason prosecutions to target and silence legitimate political opposition. The Framers of the Constitution were keenly aware of this, and thus, the Treason Clause was included to establish a clear and narrow definition of treason, preventing its misuse. This definition specifies that treason consists of only two types of conduct: "levying war" against the United States or "adhering to their enemies, giving them aid and comfort."
The clause also sets forth important requirements for proving treason charges, protecting individuals from unfounded accusations. For instance, it mandates that a conviction for treason requires the testimony of two witnesses to the same overt act or a confession in open court. This safeguard ensures that treasonous intent cannot be inferred solely from circumstantial evidence or the testimony of a single witness.
The distinction between traitorous actions and treasonous thoughts is critical. Departing from English common law, which recognised constructive treason, the Constitution requires an overt act—a concrete action that demonstrates treasonable intentions. This distinction aligns with First Amendment values, protecting individuals from being convicted based solely on their beliefs or conscience.
In court interpretations, "levying war" has been interpreted to mean the actual waging of war, requiring an assemblage of people united in a treasonable purpose. This interpretation sets a high bar for prosecution, as Chief Justice Marshall emphasised that there must be an "actual assembling of men" for such a purpose to constitute treason.
In conclusion, the Treason Clause in the US Constitution serves as a safeguard against false prosecutions by narrowly defining treason, setting rigorous evidentiary standards, and distinguishing between actions and thoughts. It protects citizens from oppressive government practices while also recognising the seriousness of betraying one's nation.

The Supreme Court has clarified what it means to 'aid or comfort' enemies
The Constitution of the United States specifies that treason shall consist only in "levying war" against the United States or "adhering to their enemies, giving them aid and comfort". The Supreme Court has clarified what it means to aid or comfort enemies through a few cases, including Cramer v. United States and Haupt v. United States.
In Cramer v. United States (1945), the Supreme Court considered whether an "overt act" must manifest a treacherous intention or if it was enough that other evidence supported such an intention. The Court held that the Treason Clause's "two-witness principle" prohibited "imputation of incriminating acts to the accused by circumstantial evidence or by the testimony of a single witness". In other words, every act, movement, deed, and word of the defendant charged with treason must be supported by the testimony of two witnesses.
In Haupt v. United States (1947), the Supreme Court sustained a treason conviction for the first time in its history. The defendant was charged with harbouring and sheltering his son, who was an enemy spy and saboteur, and assisting him in purchasing an automobile and obtaining employment in a defence plant. While these acts might naturally be performed by a father for his son, the Court held that this did not necessarily relieve them of the treasonable purpose of giving aid and comfort to the enemy. Justice Jackson stated that "no matter whether young Haupt's mission was benign or traitorous, known or unknown to the defendant, these acts were aid and comfort to him". The acts were considered "more than casually useful" and were "aids in steps essential to his design for treason".
The Court further clarified that conversation and occurrences long prior to the indictment were admissible as evidence of the defendant's intent. Additionally, the requirement of two witnesses to the same overt act or confession in open court does not exclude out-of-court confessions or admissions if corroborated by the testimony of two witnesses.
These cases illustrate the Supreme Court's interpretation of what constitutes "aid and comfort" to enemies in the context of treason, providing guidance for future treason cases.

Treason is the only crime defined in the US Constitution
Treason is the only crime that has been defined in the US Constitution. The Constitution's framers shared the centuries-old view that citizens owed a duty of loyalty to their nation. However, they included the Treason Clause to guard against the historic use of treason prosecutions by repressive governments to silence legitimate political opposition.
The Constitution defines treason as "levying war" against the United States or giving its enemies "aid and comfort". It specifically identifies what constitutes treason and limits the offence to only two types of conduct: firstly, levying war against the United States; and secondly, adhering to the enemies of the United States and giving them aid and comfort.
The term "levying war" refers to the act of assembling for a treasonable purpose. It requires actions against the United States, not just a conspiracy. In other words, it means open action against the United States through the use of force. In the case of Ex parte Bollman (1807), Chief Justice John Marshall emphasised that there must be an actual assemblage of men, for the treasonable purpose, to constitute a levying of war.
The Constitution also specifies the requirements for conviction. A person cannot be convicted of treason unless there is testimony from two witnesses to the same overt act, or a confession in open court. This was confirmed in Cramer v. United States (1945), where the Court held that the constitutional requirement of two witnesses to the same overt act does not exclude out-of-court confessions or admissions made by the accused.
