I want to know the answer to the following question:
Who was the United States' first President?
All the background I'm provided with is that "In 1789, the first President of the United States, George Washington, was inaugurated; the first United States Congress and the Supreme Court of the United States each assembled for the first time, and the United States Bill of Rights was drafted, all at Federal Hall on Wall Street.". Is that enough to answer the question?
