A group of more than 100 former state attorneys general is asking President Barack Obama to pardon former Alabama Gov. Don Siegelman, who's serving a prison sentence for bribery.

The letter was sent to the White House on Wednesday.

Former New York Attorney General Bob Abrams said they believe the Democrat's conviction was unjust and tarnished by politics.

Siegelman was convicted in 2006 of selling a board appointment to HealthSouth founder Richard Scrushy in exchange for contributions to his 1999 campaign to establish a state lottery.

Presidential intervention is Siegelman's final hope of getting his prison sentence cut. Appellate courts have upheld his conviction.

Siegelman was sentenced to more than six years in prison. The 70-year-old former governor will be released in 2017.
