The Chicago Sun-Times reported the Democratic governor made the comment at a Thanksgiving visit to the Chicago Christian Industrial League.
"I always err on the side of compassion," Blagojevich said. "I think people make mistakes."
The former Republican governor, 74, "has paid a significant price" for his federal racketeering and fraud conviction, Blagojevich said.
Blagojevich was elected governor in 2002. His administration is the target of a federal corruption investigation.
