Okay, this is all fun and games until someone other than El Cheato gets hurt.
Here's what I really think these tweets are - they're posted by someone with absolutely no access to the inside of the shithouse whitehouse. But (s)he knows someone who knows someone, and is just removed enough that even if (s)he should be 'caught', the actual source of the leaks cannot be identified - (s)he could claim to have made it all up. Whatever is actually coming from the inside source is almost certainly being enhanced and expanded by the tweeter, the intermediaries or both. That serves to both inflate the entertainment value and to insulate the perps from investigation. But there is a grain of truth still embedded in the final product (the tweets).
No other scenario makes any sense to me. But it's still fun to pretend that this is an open channel to the seamy underbelly of the undeniably corrupt, chaotic and malicious whitehouse and it's nefarious plans.
