The Reverend Jesse Jackson is also speaking out about his congressman son's condition.
Jackson spoke at the Rainbow PUSH Coalition's headquarters where he said his son is under tight medical supervision at his home in Washington, DC.
"It takes time, and I hope nothing will interfere with his quest for health first and his work second. He'll be alright in time, but it will take time," he said.
Jackson Jr. was released from the Mayo Clinic on Friday.
It is not clear whether the congressman will be campaigning for re-election.
He has been on medical leave since June.
