The main purpose of this legislation is to address concerns about how the national debt and the interest payments on that debt could threaten the national security of the United States. It aims to ensure that lawmakers have a clear understanding of these risks and can take appropriate actions to mitigate them. Key provisions of the legislation require the Secretary of the Treasury, in collaboration with the Secretaries of Defense and State, to produce a report detailing the national security threats posed by rising national debt and interest payments.
