Sarah Palin: Daughter Bristol’s Pregnancy ‘Devastated’ Me

Before Oprah's highly anticipated sit-down with Sarah Palin on Monday, Barbara Walters is releasing clips of her own upcoming interview with the former Alaska governor.

Palin tells Walters she didn’t realize her teenage daughter Bristol was sexually active, so she was stunned to learn that Bristol and Levi Johnston were expecting a child.

“That’s why I was shocked,” Palin says. “Truthfully, we were devastated.”
