Buffet has been buying politicians for decades. Unlike most of his subsidiaries, his railroads at least provide a real service, even if it isn't price competitive with a pipeline for oil. His big cash cows -insurance- profit from government regulations and banking cartel (another government sanctioned monopoly) contractual requirements that every driver and property owner buy wasteful insurance that they don't want.

Well of course. Take care of your friends first. He has a long line to go yet.
