In an interview with Oprah Winfrey in 2010, Bristol was questioned as to whether her abstinence pledge was a "realistic goal."
"It may be 10 years before you get married. Why set yourself up so that everybody you go out with, you date -- the media is going to be looking at that person, trying to get that person to sell you out, to say, 'Did you have sex or not?'" Oprah said. "It's not anybody's business when you chose to have sex."
Bristol said she didn't think she was setting herself up to fail. "It's a realistic goal for myself," Bristol added.
Oprah even gave Bristol the chance to go back on her statements about withholding from sex. "I'm going to give you a chance to retract or ease that statement if you wanted to and not say categorically, 'I'll never have sex until I'm married,'" Oprah said. "But if you want to hold to that, may the powers be with you. So you're going to hold to that?"
Bristol's mother Sarah then asked a surprising follow-up question. "Does that mean you're going to marry pretty young?" the Republican vice-presidential candidate inquired.
"I don't know, Mom," Bristol replied.
Sarah added, "I'm telling her, don't think she has to find a man and marry young. The world is her oyster and she's going to be able to pursue an education and career and avocation opportunities without a man."
On Thursday, over five years after this interview took place, Bristol announced that she's pregnant out of wedlock.
"I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you," she said of her second pregnancy. "I do not want any lectures and I do not want any sympathy. My little family always has, and always will come first. Tripp, this new baby, and I will all be fine, because God is merciful."
