(CNN) - A day after announcing his position on abortion had undergone a "transformation," Texas Gov. Rick Perry clarified that he would make an exception if a mother's life was in danger.
On Tuesday, the Republican presidential candidate told a crowd in Iowa that he had toughened his stance on abortion after viewing a documentary produced by former Arkansas Gov. Mike Huckabee. Perry said he had changed his position to oppose abortion, even in cases of rape or incest.
When he was pressed about the change Wednesday, Perry said his he would allow for abortion when a woman's life was at risk. He said such cases were the only ones in which he thought abortions were acceptable.
Perry recently signed the Personhood USA pledge to advance legislation protecting human beings "as persons at every stage of development."
The pledge doesn't say precisely whether abortions should be permitted if a woman's life is in danger, stating only: "I recognize that in cases where a mother's life is at risk, every effort should be made to save the baby's life as well."
Perry said again Wednesday that his transformation on abortion came after watching the Huckabee film, "A Gift of Life," and after a conversation with Rebecca Kiessling, who is known among abortion opponents for speaking about her life story, which begins with her conception as a result of rape.
"I really thought about this through the Christmas holidays," Perry said. "That's the conclusion I came to after (Kiessling) looked me in the eyes and said, 'Why would my life not be worth saving?' And I didn't have an answer."
