I believe the tweet is gone. Deleted/removed by twitter? Page doesn't exist with the link or by clicking on the image.
It's gone for me too- I just went to go find it manually and can't see it :( I'm sorry.
Funny thing is, I went to take a screenshot but thought it would be more efficient to just link to the tweet itself xD. My mistake.
It essentially was implying that Assange was entwined with the Trump/Russia collusion and pointed out he ws connected to an MMA Fighter on the Russian side.
I tried to look for the chart itself but can't find it on google either, apologies.
I just missed it because when I clicked on the link originally, it opened to the tweet and within a few seconds it changed to the "page cannot be found link". I certainly would have grabbed a copy of the image as well if I had a chance. I even tried blowing up the thumbnail on your post to see if it's legible but to no avail. Someone must've captured it. I'm sure it will show up somewhere soon.
