$2.4 million accepted in bribes, by California Republican Representative Randy "Duke" Cunningham, to steer defense contracts. There is not much lower you can go.
This is one reason that I don't really care about immoral CEOs. They don't actually have the power to steal your money directly, without some kind of government help.
It's also why lawmakers need less power and less money, not more. Of course bribes are going to be offered, when they have the power to spend so many billions, through contracts, subsidies, and anything else they please.
