Newark Mayor Cory Booker says he didn't feel brave, but did feel terrified as he dashed through flames with the woman over his shoulder.
Booker returned home Thursday night to find his neighbor's home on fire. He was aided in the rescue by his security detail.
Booker described the rescue as a "come to Jesus moment."
Booker was treated and released from a hospital after suffering from smoke inhalation and second-degree burns on his right hand.
The woman is in stable condition with second-degree burns.
Booker's security detail helped three others escape.
A fire official says the cause of the fire may be cooking-related.
