The purpose of this legislation is to ensure that anyone who temporarily takes on the role of Director of National Intelligence (DNI) has the necessary qualifications and expertise in national security. This is important because the DNI plays a critical role in overseeing the nation's intelligence agencies and ensuring national security. The key provision of this legislation is an amendment to an existing law that specifies the qualifications required for the DNI. It states that any individual serving as the acting DNI must have extensive national security expertise.
