I guess you conveniently overlooked that it was Trump's crew, the Russians and the Russian press at that event. 
No American press admitted! How's that for logic? The fewer participants, the fewer sources for leaks, eh!
What would either of them gain?  Who knows, but it certainly doesn't look good on Trump; either he is blabbing too much or someone on his hand-picked crew has it in for him. Either way it goes right back to Trump i.e. not all that smart.
