What was done is "ops normal"; a VIP (of any stripe) is coming, you find out their position on relevant issues, special requirements, their favorite beverage, etc. You'll see this done by competent staffs anywhere, for any visitor who can influence the destiny of an organization. Failure to do so is negligence, possibly incompetence. I've watched the same sort of thing done for O-6s, so a Congressman is a no-brainer.

The point of a "dog and pony show" is to gain support, both tangible and intangible, for a unit, from people who may not understand the unit's role and requirements.

To have a MISO (Military Information Support Operations; the new name for Psyops [unless doctrine has been rewritten... again]) unit doing this job, even an otherwise underemployed MISO unit, shows a lack of forethought. You have to procede from assumption that it will hit the front page of the NY Times, and ask yourself, as a leader, "How will this look?"

One of the things the Army needs to learn from the Air Force is to explain this to junior officers. Honorable young Army LTs are routinely horrified at the basic realities of the budget process and appear to feel that basic courtesy and protocol is "brown-nosing", deceitful, and pretty much beneath them. When they make major, there can be significant trauma from exposure to the basics of getting funding for the LTs fundamental needs. An LT doesn't need to learn the entire five year budget process, but should understand that funding doesn't 'just happen' (no matter how hard and honestly you work), and that the process for getting funding doesn't always meet with their standards of conduct.
