The purpose of the meeting is to fulfill an Arrow of Light requirement called "Building a Better World." The Arrow of Light is the highest award available to Cub Scouts, requires a significant amount of effort to earn, and is the only Cub Scout award that carries over into Boy Scouts. On the Boy Scout uniform, it is worn underneath the left breast pocket of the Class A shirt. 

Here is the specific requirement as written in the Cub Scout manual: Meet with a government leader and learn about his or her role in your community. Discuss with the leader an important issue facing your community. 

Seems to me that Ames more than met the requirement, especially the second part of it. Good for him! I see a bright future for this passionate young man.
