Hillary Clinton just added fuel to the fire of speculation surrounding her questionable physical condition this morning by apparently collapsing while leaving the scene of a 9/11 commemoration ceremony in New York early.

Short amateur video (above) shows her waiting unsteadily for her van to arrive, then collapsing as at least three handlers help, if not actually carry, Hillary into the back of the vehicle. A close look reveals her feet dragging before Secret Service and others crowd around to protect her and obscure the view. NYPD were reportedly dispatched to retrieve one of Hillary's shoes afterward.

Fox News reported that a source standing very close by said she was “clearly having some type of medical episode.”

Hillary's spokesman Nick Merrill later issued a statement saying the former Secretary of State "felt overheated," despite the fact that it was not a hot day:

"Secretary Clinton attended the September 11th Commemoration Ceremony for an hour and thirty minutes this morning to pay her respects and greet some of the families of the fallen. During the ceremony, she felt overheated so departed to go to her daughter's apartment, and is feeling much better."

A senior aide told Fox News "she is fine."
