Why did general MacArthur address congress after he was fired.?

Gen. Douglas MacArthur’s farewell address to Congress on April 19, 1951. MacArthur was invited to speak to a Joint Session of Congress after he was fired by President Harry Truman for having made critical statements about Truman’s policies as it related to the Korean War. MacArthur spoke eloquently in his speech about the nobility of the American Soldier, and closed with his famous statement, "Old Soldiers never die, they just fade away." This speech is a masterpiece of public speaking, whatever you think of Truman’s decision to fire MacArthur.
