Final answer:
The State of the Union is the annual event where the president addresses the nation, reporting on national status and legislative priorities to a joint session of Congress and the public.
Step-by-step explanation:
The annual event where the president addresses the nation is called the State of the Union. According to the Constitution, the president is required to report on the 'State of the Union' to Congress every year. This address has evolved into a key moment for the president to present their legislative agenda and strategic plans to both Congress and the American public, though it is important to note that the agenda set forth in the State of the Union is not binding on Congress, and ultimately, only a portion may become law.
The State of the Union Address is delivered to a joint session of Congress, generally in January, and is broadcast nationally, providing an opportunity for the president to highlight accomplishments, set policy priorities, and unify the nation under a shared vision for the future. While the State of the Union is one of the most notable presidential addresses, presidents also speak on various other occasions, such as inaugurations, memorial services, and party rallies, communicating on issues of national significance and advocating policy positions.
