Not really much to say on this one, except check out this brilliant graphic (source) that shows the links between Monsanto and US Congress.
Here’s one example:
When Monsanto got approval for use of its artificial bovine growth hormone in milk, the person in charge of preparing the report at Monsanto was Margaret Miller. Later, the person in charge of receiving the report and evaluating it was… wait for it… Margaret Miller! By then Deputy Director of Human Safety and Consultative Services in the office overseeing the process.
