The first loyalty of the US Constitution is to the people, not the president.

There should be no secrets or concerns by the people of the USA of their president. None. Secrets of a president of the USA is called “compromised “ especially in international affairs. There is a very good reason for at least one person in the government to review a president’s tax returns. A very good reason. It is a national security issue.
