While retweets are not proof of anything, it does proof POTUS is aware of the matter. He is in charge, he can take it from here but learn to archive.
Happy that he acknowledged it regardless of what the outcome, it would or could fester into something that ill serves. It is a tall tale that I doubt gets unwrapped properly before the the election, but does not paint his opposition in a good light until then. Whatever the reason, holy shit can you imagine having to rewrite so much history?
