Supporters of Jamie and Gladys Scott hope a rally later today will put pressure on Mississippi Gov. Haley Barbour to pardon them for a crime they committed in 1993.

The sisters were released from prison after serving 16 years of a life sentence earlier this year on the condition that one donate a kidney to the other.

"I wouldn't hold my breath," Barbour told the Associated Press when asked about a pardon, adding: "Tell 'em don't save any space in the newspaper for that to be announced."

A spokeswoman for the governor said he doesn’t grant pardons to people who don’t admit their guilt and express remorse.

The sisters were convicted in 1994 for participating in the robbery of two men in 1993. Just $11 was netted in the robbery.

The Scotts’ attorney plans to lead a rally in front of the governor's mansion to raise support for a pardon request he's filing. He said a pardon could help the women find jobs, according to the Associated Press.

Jamie Scott suffers from kidney failure, and Gladys Scott offered to donate a kidney to her. Both women have been told they need to lose weight before the procedure can be done.
