Brought this up many many breads ago.
I still hold to theory they were trying to poison POTUS until a better explanation is found. A few days prior to this they POTUS did an interview a with piers Morgan and they where talking about a presidential aide specially for bringing POTUS water and how a napkin was placed on top of the glass to prevent poisoning.
It was all people discussed about the interview.
Coincidence?
What if he was gesturing to specific Dems?
He didn't drink it, just raised the glass and gave that sly knowing grin.
Watch the Water.
What if the phones in question during SOTU had something on them like, Damn he didn't drink the water, he always takes a sip, now what the hell are we going to do?
Be nice to see what was really being discussed on those phones.
Just a theory - for now.
Future proves or disproves past.
