Obviously, Junior was going to enquire about the dirt—you can basically assume that, since he thought dirt would be the topic.
He said very plainly in his e-mail exchange with Goldstone that the meeting was about getting dirt. Adoptions never came up in any of the e-mails between Goldstone and Uday. Now what's really ridiculous about your defense is that you're admitting that Uday went there to get stolen dirt on Clinton, which is against the law. So you're admitting that the President's own son was colluding with Russia to get stolen e-mails on Clinton. You're trying to distract with "adoptions" when the only indication you have that was a subject was a memo dictated post-hoc by Trump himself.
I don't understand why a reasonably intelligent person like you wouldn't believe the shit you're seeing with your own eyes, and why you're stooping to such lows and going to such extreme lengths to defend Trump. It feels to me like you have hitched your wagon permanently to that wreck, and rather than admit you were conned you double down on it. I don't understand why. You don't owe Trump anything.
