As to the Q question What ROLE is TG being cleared to go into.
ROLE is capitalized and may be an acronym here, An acronym finder stated that in military and government it stands for Rule Of Law Effectiveness which is summed up by these principles: https://en.m.wikipedia.org/wiki/Rule_of_law
So maybe Gowdy is going to be part of some effort to hold government officials who have broken the law legally accountable for their actions in whatever position he gets put into.
Thank you for the reference, an extensive, and very helpful, exposition on the “rule of law.”
