Shortly after that picture was taken...
Hillary raised her hand to her forehead like she was feeling faint, and an aide
(wearing a brown/white striped half-sleeve top)
quickly slapped Hillary's hand down and away from her forehead,
So instead, Hillary brought her fist to her mouth, and coughed once into her hand.
Then Cuomo signaled for Hillary to turn right and get out of that crowd.
It took Hillary six shuffling steps for her to turn 45 degrees to her right
and she looked unstable as she made that turn.
The woman wearing the brown/white stripes who slapped Hillary's hand away from her forehead
appeared to possibly be Hillary's doctor, Lisa Bardack.
