One of my anglers a few years back had a few go-rounds with one or more liberal congressional types... The deal is pretty simple -but not generally understood... All you need is a few congress types in your corner (however you have to do it...) then you can either put your competition (or almost any business, for any reason...) in a very bad way - particularly it they're facing a subpoena from one committee or other... That business, or activity group then has to spend almost a year prepping to appear (as well as going through every single document they will be required to provide..). For a great big corporate entity (use Facebook as an example) they will not suffer much at all from this sort of harassment since they employ substantial resources to deal with records requests, as well as lawyers, PR types, etc. to prep whichever executive will be appearing in front of whatever committee... A relatively small business - say a small consulting firm can be really badly hurt by this sort of stuff since all the time and money spent defending yourself or your policies in front of some committee won't do anything for your bottom line - in fact your competitors will benefit since they don't have any similar drags on time, money, effort...
Once you learn about this sort of stuff (and the tame legislators that are always willing to accept requests from big donors - or just powerful companies....) you begin to understand why companies cave in advance to lower their profiles and make as certain as they can that someone else gets "run up and down the flagpole" - publicly.... This is pretty corrupt in my opinion but there's a reason companies employ a variety of advisors, lobbyists, etc.
Thank heavens I live almost as far south of Washington as possible... Hope I spend the rest of my life staying out of courtrooms, public hearings, and especially Washington.... That "swamp" everyone talks about has been there from the beginning more than 200 years ago - and it will still be there long after our current administration becomes history (hopefully after a second term... ).
