Exactly. It’s a false narrative. Technically it’s not wrong because he said around the same time. Which means nothing but the impression it gives is that they did it for Trump.
The Mueller report is full of exact dates but here they say “about the same time”. As you said, just to create a misleading impression. It’s not even sequentially correct according to the facts mentioned in the OP.
And while we’re at it, it was Clinton who brought Russia into it when she accused Russia of hacking her server. Trump didn’t insert Russia into the conversation, Clinton did. Trump poked fun at her foibles with his remarks.
Though I admit I don’t know for certain if Trump didn’t mention it before July 26th this post claims that was the first time. In any case, it was Clinton who brought Russia into the conversation first.
But, Mueller does claim Trump campaign first started chattering about it in June, and Mueller claims WikiLeaks first released emails in June but we know that WikiLeaks first put up some of the emails three months prior. So it has to be intentional - or so ridiculously sloppy esp considering Papadopoulos was indicted for getting the date of his Downer meeting wrong.
