If everything we have been told up to now about the Trump camp colluding with the Russians to steal the election from Hillary, then what Jr did is a non story. Collusion would have already happened. 

Everyone is focusing on the dirty on Hillary, I think any dirty on Hillary was fairly will known before this meeting, she'd been in public service for 30 years. However, want if Jr went to see if this lawyer had dirty of his father that the Hillary camp could use? This whole thing is base on a conspiracy theory, because there's been no evidence. No collusion happened, because Jr got nothing, the lawyer got nothing, the meeting ended in twenty minute. To collude something has to be exchanged.
