Your link was not working but I watched the interview...
It was Assange repeatedly ducking the question...
Meanwhile... BEFORE the leaked emails, it was clear Russia was behind the hack...

Within 24 hours, CrowdStrike had installed software on the DNC’s computers so that it could analyze data that could indicate who had gained access, when and how.

The firm identified two separate hacker groups, both working for the Russian government, that had infiltrated the network, said Dmitri Alperovitch, CrowdStrike co-founder and chief technology officer. The firm had analyzed other breaches by both groups over the past two years.

One group, which CrowdStrike had dubbed Cozy Bear, had gained access last summer and was monitoring the DNC’s email and chat communications, Alperovitch said.

The other, which the firm had named Fancy Bear, broke into the network in late April and targeted the opposition research files. It was this breach that set off the alarm. The hackers stole two files, Henry said. And they had access to the computers of the entire research staff — an average of about several dozen on any given day.

Trumps campaign only insisted on ONE thing in the Republican Platform, and that was to remove language regarding Russia's aggression on the Ukraine"

One noticeable change is found in the Republican Party’s radical departure from its anti-Russia position. Suddenly, Republicans are cool with Vladimir Putin’s war of aggression against the Ukraine. While a radical change, it’s not surprising when you consider Donald Trump’s public declarations of admiration the Russian dictator.

Trump wanted this very badly because, as Josh Rogin points out, his employees worked hard to prevent the Republican Party from calling to give Ukraine weapons to defend itself.

The story began when Diana Denman, a Cruz supporter, proposed a platform amendment calling to maintain or increase sanctions against Russia, increase aid for Ukraine and “providing lethal defensive weapons” for the Ukraine military. After attempting to water the amendment down, Trump staffers wrote an amendment to the amendment to replace the call for “lethal defensive weapons” with “appropriate support.” That amendment passed.

When you combine this with Trump’s public affection for the dictator who praised him, it isn’t a stretch to conclude that Trump places a higher premium on making nice with said dictator than on inconsequential things like having our allies’ backs and national security. Of course, the wall will fix everything, right?

And he has said he will look into lifting sanctions on Russia for their annexation of Crimea:

Donald Trump said Sunday that Russian President Vladimir Putin won't make a military move into Ukraine -- even though Putin already has done just that, seizing the country's Crimean Peninsula.

"He's not going into Ukraine, OK, just so you understand. He's not going to go into Ukraine, all right? You can mark it down. You can put it down. You can take it anywhere you want," Trump said in an interview with ABC's George Stephanopoulos on "This Week."
"Well, he's already there, isn't he?" Stephanopoulos responded, in a reference to Crimea, which Putin took from Ukraine in early 2014.
Trump said: "OK -- well, he's there in a certain way. But I'm not there. You have Obama there. And frankly, that whole part of the world is a mess under Obama with all the strength that you're talking about and all of the power of NATO and all of this. In the meantime, he's going away. He takes Crimea."

Not sure how that last bit can be read in a coherent way...

Stephanopoulos interjected to note that Trump has suggested he could recognize Russia's claim on Crimea over Ukraine's -- and Trump didn't back away from that possibility in the interview.
"I'm going to take a look at it," he said. "But you know, the people of Crimea, from what I've heard, would rather be with Russia than where they were. And you have to look at that, also ... just so you understand, that was done under Obama's administration."
Trump added: "And as far as the Ukraine is concerned, it's a mess. And that's under the Obama's administration with his strong ties to NATO. So with all of these strong ties to NATO, Ukraine is a mess. Crimea has been taken. Don't blame Donald Trump for that."
The Clinton campaign responded later Sunday, with senior policy adviser Jake Sullivan saying: "What is he talking about? Russia is already in Ukraine. Does he not know that? What else doesn't he know?"

And you know DAMN well that if Clinton had called for a foreign power to commit a crime in an attempt to influence the election, Congress would be having an investigation IMMEDIATELY.
