"...
Rob Goldstones emails afterward: On June 14, 2016  five days after the meeting  Rob Goldstone emailed his boss Emin Agalarov and fellow meeting attendee Ike Kaveladze a CNN story in which the DNC went public to claim that theyd been hacked by Russians. Goldstone wrote that the story was eerily weird given what theyd just discussed at the Trump Tower meeting. (This full email also hasnt yet been released.)"
Trump Russia news: Mueller investigation focused on Trump Tower meeting - Vox
		 
		
	 
First off, no one knows what Mueller's investigation is or isn't focussing on.
Second, this Trump Tower contact falls far short of any evidence of collusion and can actually be used to counter such allegations.
The available evidence, including the narrative of the special counsel, shows an effort to use Papadopoulos as a conduit to Trump, and while Papadopoulos comes across as something of a village idiot, he did not hide those contacts. 
The Trump Tower is even weaker as evidence of collusion. According to people like Schiff, this was smoking-gun evidence of a secret Russian conspiracy.:crazy::crazy:
However, the meeting occurred in June 2016 when the hacking was already known publicly. As with the Papadopoulos contacts starting in March 2016, 
the meeting is rather late for an effort at collusion. Disclosure of the Russians hacking the DNC and Clinton campaign had already been made by the FBI in the prior year and was known at least in September 2015 by the FBI. In June 2016, the Washington Post was reporting on hacking of the emails.
Moreover, the Russians used a British music promoter familiar with Donald Trump Jr. to secure a meeting with the promise of evidence of unlawful contributions made to the Clinton Foundation. 
There was no effort to limit the participants or hide the meeting. This secret operation supposedly was advanced with a meeting at Trump Tower with an army of reporters outside and no prior knowledge of who would be present. The brief meeting primarily discussed the lifting of a federal ban on Russian adoptions. If anything, the meeting would indicate that, in June 2016, the Russians were still trying to make contact with the Trump campaign.
Does it really track that Russian intelligence was running a disinformation and hacking campaign but sought to collude with Donald Trump Jr.? If so, the meeting was curiously late and public for that purpose. 
Moreover, critics continue to refuse to recognize the different treatment given these contacts with Russians and the contacts of former British spy Michael Steele, who authored the controversial Trump dossier.
That effort was subsidized by the DNC and the Clinton campaign, but the funding was hidden and denied until much later. Steele reportedly received information from Russians with alleged ties to the government to be used against Trump. 
Yet, it is evidence of collusion to attend a meeting with Russians who said that they had evidence of illegal activities by Clinton, but it is not collusion to pay for a dossier with information from Russians and other foreign sources implicating Trump.:good!::good!:
