The Trump government has released a transcript and video of the joint press conference Trump and Putin held immediately after their Helsinki meeting. As you will no doubt recall, it was televised live. During that press conference, an American reporter asked Putin whether he had wanted Trump to be elected President, and Putin said [or the interpreter represented him as saying] "yes."
In the transcript just released by the White House, this exchange is missing. On the video, it has been excised.
I do not think we need speculate anymore about whether Trump desires to be an authoritarian dictator on the Orwellian model. The only question remaining is whether he will succeed.
