Final answer:
An Executive Order is likely to be found in the Presidential documents section of the Federal Register, which includes various administrative documents issued by the President.
Step-by-step explanation:
You would likely find an Executive Order in the Presidential documents section of the Federal Register.
The Federal Register categorizes documents into four sections, but Presidential documents are specifically allocated for administrative documents like Executive Orders, due to their nature as directives from the President to those working in the executive branch on how to implement legislation.
The Presidential documents section also includes other directives, such as signing statements, as well as any memorandum, notice, determination, letter, or order issued by the President.
Considering their significance, such as the Emancipation Proclamation or the creation of the Environmental Protection Agency, the Presidential documents are essential to understand the policies and changes being implemented at an executive level.
