Originally as reported by Dan Rather, Senator Kerry injured his back while rescuing a very large female union member trapped in a toilet stall prior to the event.
However after video footage was reviewed of the events onstage during the rally, it is obvious that the injury was sustained when Jimmy Hoffa Jr., teamsters union president was speaking.
Senator Kerry is clearly seen in the background attempting to bend over between his legs far enough to be able to kiss his own butt!
During this unique contortion, Senator Kerry is seen suddenly grabbing his lower back and grimacing in pain.
Most experts believe this is when Senator Kerry actually injured himself.
Dan Rather or CBS could not be reached for comment....
