LOL you beat me to it.
I wouldn't describe them as equals, however.
This is only speculation, but it's informed speculation (I know a lot of political deep-insiders, mainly as an accident of birth......) I predict that, if we ever find out the whole story (and that's an unlikely if), we'll learn that it wasn't AM who approached DH to ask him to serve as his attorney. We'll learn, instead, that it was DH who approached AM, to say, "You need me as your attorney"....and both of them would have understood that to mean, that AM did not have a choice in the matter.
