Answer: The President of the United States
Explanation: The President of the United States is responsible for delivering the State of the Union address. This is outlined in the U.S. Constitution, which states in Article II, Section 3, that the President "shall from time to time give to the Congress Information of the State of the Union, and recommend to their Consideration such Measures as he shall judge necessary and expedient." The President has been delivering the State of the Union address since the first one in 1790 when George Washington delivered it to Congress. Since then, it has become a yearly tradition that the President delivers a speech to Congress and the nation to update them on the state of the union and the issues that must be addressed.
