Do you have a link showing a 12/28 date. Everything I look up says 12/29.
I searched (very briefly) for such a link.
In this article, the Russians left for Russia Dec 31. I recall they were given 72 hours to vacate (remember, they had families and had occupied aka “lived in” their diplomatic compounds for perhaps years.
Counting back from Dec 31, we would have Dec 30-29-28. It may well be that the NEWS REPORTS as to the expulsions occurred Dec 29. It would be possible that this executive act by 0bama occurred on Dec 29, but to me it’s more likely to be pm news Dec 28th.
Maybe I am completely wrong, but I think my version of events that led to the K-F phone call are 100x as plausible as the theory advanced in the article, namely, that K was a willing participant in 0bama’s plan to shank either Flynn or Trump. Flynn told K to “chill” and try not to retaliate. Sanctions were not discussed.
