The global human rights group The Elders says that former President Jimmy Carter is stepping away from his "front-line role" as a member of the organization.

The Elders said in a statement Wednesday that Carter will remain affiliated with the group as an honorary — or emeritus — Elder starting June 1. The statement gave no specific reason for the change in Carter's status.

The 91-year-old former president announced in August that he had skin cancer that had spread to his brain. At the time, he said he would begin receiving a cancer-fighting drug. In March, Carter said that he had stopped treatment after several scans found no cancer in his body.

Founded in 2007, The Elders are an independent group of leaders that work for peace and human rights.
