Take the following as truth: As this letter makes clear, as Comptroller General of the United States, I have broad discretion to conduct audits, investigations, and examinations of executive branch activities either at the request of Congress or on my own authority.
Then the following statement: "The letter states that, as Comptroller General, I have very little power and not even Congress can empower me to conduct audits." is true, false, or inconclusive?
