Did you read? Its registered to a house in NH, the person living there is an elderly lady who is related to one of the people who formed this sham corporation. And, the people behind this took their legit businesses web pages off line today, and refused to be interviewed.
Read all the articles....there is something afoot.
There's no doubt that on the surface there's a lot of possibilities here.
But that's still not to say one can't run a legit consultancy out of one's home, nor have your mother-in-law watch the house or your kids when you're in your Boston apartment.
Here's the pertinent section you're referencing above:
"Slate’s Ruth Graham drove to the address listed as Draper Sterling’s place of business and were greeted by Jon Adkins’ mother-in-law, who told them, “I don’t know what he does. All I do is I watch his kids” before eventually conceding that “he’s in the medical field” and “does a lot of business out of Boston. Whatever he does, I don’t know.”"
Given the contacts, I can run Chomsky Consulting out of my home spare-bedroom office with nothing more than internet & phone, and if I can get you a sit-down with Obama for $25K, are you going to say it's not legit? If registered, documented, declared, and taxed - it is legit. And if you're willing to pay for that service and access, it's probably well worth it to you as well. This is exactly how a lot of political business is done in my city, often through high-powered connected law firms, and it's widely known.
So these could be legit services, or at the least portrayed as such to meet the letter of the law.
Or as you suspect, they could be some shady dealings.
I personally suspect they're the result of the Trump campaign playing fast and loose as if they're still doing transactions in private business, and it may come back to haunt them. It may even be Lewandowski running a scam (or getting set-up to take a fall).
But there's a lot of graft that takes place under the guise of consulting and lawyer's fees, and unfortunately while dealing in gray areas it often meets the technical definition of being legal (or difficult to prove it's illegal).
