TRUMP’S STATE OF THE UNION: WHO’S ATTENDING?

What else should I know?

The State of the Union address, which is an annual event, is given before a joint session of Congress. It comes from a clause in the Constitution that requires the president “from time to time give to the Congress Information of the State of the Union,” Article II, Section 3, Clause I of the U.S. Constitution reads. Former President George Washington gave the first State of the Union -- though it was not called this at the time -- in 1790.

The length of past speeches has varied. While former President Ronald Reagan’s address was about 31 minutes in 1986, former President Bill Clinton's 2000 State of the Union speech was nearly an hour and a half, according to the American Presidency Project.

In 1947, former President Harry Truman’s address was the first to be televised. And in 1965, former President Lyndon B. Johnson’s speech was the first to be broadcast during prime time.
