I doubt either one has anything credible. if they did, they would just release it instead of trying to build up attention before the release. Bombshells don't need pre release promoting.
I tend to agree with this.
I guess it's also possible that Trump has been told he will be getting the Obama transcripts from someone and would have them by the middle of the week and that is what's holding the release up. Probably just wishful thinking on my part tho.
