The members (and their staff) of the Congressional committees that deal with NASA should definitely take this course: New Approaches to Human Spaceflight Technology and Policy – LaunchSpace.
E.g. they would find these sections would particularly informative:
> 5. Myths and Realities of Human Spaceflight.
Interactive discussion and exposure of several myths: Science and Exploration, Risk and Cost, ”Only NASA can do it safely”, Why “man-rating” makes no sense in the modern era.
6. The Truth about Launch Economics.
Cost elements of launch system development and operations. Why flight rate matters more than vehicle configuration/design. The Shuttle and the economic viability of reusable launchers. Why government space hardware costs so much to develop (procurement methods, perverse incentives). Example of the British airships.
