Actually that quote is incorrect. It has been widely misquoted by the main stream media for their own propagandistic reasons.

I'll be honest, that doesn't really change my interpretation of the sentence, they already had "pro-Trump" and "pro-Russia" in quotes, which made it clear to me they didn't believe them to be as such.
It's not the semantics of the sentence that bother me, it's that they went to great lengths to get DNC and Clinton emails but just go ahead and ask the Trump campaign for information. Clearly they are treating the Trump campaign with softer gloves than the Clinton campaign.
Edit: Why the downvotes?
It doesn't seem to fully reverse my opinion of WikiLeaks although I wonder if I can really be objective now.
