Despite what she went through in the years following the attack, Harding said her faith has allowed her to persevere.
"I respect you for trying to ask these questions, but I'm here for the future and what it means to me", she told the presenting duo. And I've been nothing several times.
The movie puts us in Harding's corner early, as we meet her abrasive, frequently married, frequently single mother LaVona Golden.
