The term "Federal agency" does not include which of the following?

The term "Federal agency" specifically refers to entities established by federal law that operate under the authority of the federal government. Within the context of this question, the executive office is indeed part of the federal government, including entities such as the White House and its various offices that carry out federal policy and administration.

In contrast, general local government refers to municipal or county governments responsible for local governance and public services. These entities operate at a state or local level and do not fall under the classification of a federal agency, as they are created by state law rather than federal law.

Additionally, all agencies of the federal government naturally fit within the definition of a federal agency, as they are established and operate under federal statutes. Likewise, Indian tribes that have assumed responsibilities under the National Environmental Policy Act (NEPA) may interact with federal standards and requirements but do not constitute a federal agency themselves, as they are sovereign entities recognized by the federal government.

Thus, the executive office, being an integral part of the federal structure, is correctly excluded from the term "Federal agency" in this context.
