My limited understand of politics is that the director has a private meeting with the politician to give them a heads up on the investigation, and assures them they will handle it with utmost urgency and file the results away in a safe place, while the politician thanks them for bringing it to their attention and lets them know about a hot investment tip in the growing Ukraine energy sector, promising them a meeting with the CEO of a company about to go IPO. Then they pat each other on the back and tell themselves they're protecting Americans' trust in our sacred institutions.
