Basically, that’s the thrust of one of James Comey’s memos.
It appears more and more that there is a good reason why it has not been leaked that there is any evidence of collusion. Because there is none.
It seems that the correct version of events is that Trump’s main concern was whether or not he was being investigated. That he wasn’t trying to cover anything up, and that he fired Comey for the reason that has been reported – he was furious he couldn’t get him to publicly state the truth, that he was not under investigation.
Of course, the reason Comey would not say so has everything to do with James Comey. He had already come under criticism for reopening the Clinton investigation, and he didn’t want to experience another torrent of abuse should he have to reverse himself again and say Trump had come under investigation.
From the website Law & Crime:
One particular conversation between Trump and Comey (page 13 of the memos) was highlighted by Trump describing the Russia investigation as a “cloud” that was making it difficult for him to do his job. Trump even asked what he could do to lift the cloud. Now, that doesn’t look great on its own, but in the context of the conversation, we now know Trump was more specifically worried about people having the impression that he himself was under investigation, which was not the case at the time. Comey makes it clear to Trump that he is not under investigation, and Trump apparently asked Comey several times to make that fact known.
The most important part of the conversation comes towards the end of Comey’s account. The memo says:
“He said that if there was “some satellite” (NOTE: I took this to mean some associate of his or of his campaign) that did something, it would be good to find that out, but that he hadn’t done anything, and hoped I would find a way to get out that we weren’t investigating him.”
So not only does the full account of the conversation indicate that Trump’s main concern was people’s perception of him, not the investigation itself, it also shows that he endorsed the idea of investigating people related to him and his campaign.
