I had actually entirely forgotten I was still on the FCC thread after reading the comment I replied to, but sure, the FCC is also a good example of this. Take net neutrality for instance. That whole debate was centered on what the FCC would do - very little talk about legislative action. It is de-facto up to one agency that answers to an executive with all-time-low levels of public confidence, that also has an abnormally strong reputation for being in bed with industry. The current chairman has joked about it and been investigated for corruption, the prior chairman was formerly a major lobbyist for telco. There's other examples, like the revolving door between the FDA and Monsanto's board (I'm like 90% sure I'm correctly remembering the agency and the company - I'd double-check myself but I need to get back to a work issue and wanted to answer you soon-ish).
