Imran Khan has been called the "Ron Paul of Pakistan" and he's a frontrunner for the next Prime Minister of Pakistan.
He also used to be a champion Cricket player.
During the rally he was standing on a lift when he suffered a terrifying fall after too many people got on it at the same time.
He was rushed to a hospital for treatment immediately after the 15 foot fall and is currently in stable condition.
Hundreds of supporters gathered outside of the hospital chanting "Love live Imran Khan."
