Final answer:
Americans can be convicted of treason without a confession or at least two witnesses to the treason.
Step-by-step explanation:
The statement that Americans cannot be convicted of treason without a confession or at least two witnesses to the treason is False. According to the United States Constitution, Article III, Section 3, treason is defined as levying war against the country or adhering to its enemies, giving them aid and comfort. To convict someone of treason, the Constitution requires either the testimony of two witnesses to the same overt act of treason or a confession in open court. However, this requirement applies to all individuals, regardless of their nationality.
