Answer: To ensure the President is not lying to the people.
Explanation:
The State of the Union is a very important speech by the President and acts as an official update on the affairs of the country. As a democracy, it is important that ordinary Americans know what is going on in their country.
This is why it is important that whatever the President says is fact-checked to ensure that they are not misleading the nation on how the United States is doing.
