THAT is why they put out that cover story 3 days ago:
“Hillary had to have ear surgery in her left ear...”
It’s to pre-neutralize any questions about her EAR.
“Transmitter..? ‘Tis to laugh..! SURGERY..! You’ve been watching too many episodes of X-Files..!!!”
Yep she can use the ear surgery BS to cover up the fact that she has an EAR PIECE which she will have at the debate
