Nice try, wing nut. I doubt this is the last we'll hear about the Russia investigation. Sounds more like a new beginning to me.  Legal experts have already weighed in on the collusion. Issue and find the Donny Jr. likely broke the law. Let's not forget Kushner and Manfort were there too. 
There is no excuse or reasonable explanation for the meeting unless it was done to get intel on Clinton from the Russian government. It's telling that Trump accepted that the Russian government would even offer the information.  
Yeah, nothing shady about the whole deal.
