Yes Treason is defined as the only crime in the US Constitution because under English law; anyone was tried for treason by the whim of the court. It should be noted that those who wrote the constitution quickly admitted that the constitutional definition is for "citizens who owe no duty" (have no oath of office) and leaves normal treason (by government officials) untouched.

Treason is punishable by death. If a death sentence is not imposed, defendants face a minimum penalty of five years in prison and a $10,000 fine (18 U.S.C.A. § 2381). A person who is convicted of treason may not hold federal office at any time thereafter. (West's Encyclopedia of American Law, edition 2. Copyright 2008 The Gale Group, Inc.)
