Presidential proclamation (United States).

A presidential proclamation is an official announcement from the president of the United States. These announcements usually deal with policies of the federal government. Some presidential proclamations deal with ceremonial events or commemorations. However, presidents have also used proclamations to create more substantive policies, including changes to tariffs and trade policies. All modern presidential proclamations are published in the Federal Register. They are also printed each year in the Code of Federal Regulations.
