>> chelsea arrived at stanford on air force i. was welcomed by fans and friends. she had a secret service detail, but hillary still tried to make it as normal as possible. >> my mom put contact paper, like, in every drawer. she kept, like, trying to find things to reorganize and finally my dad was like we need to go. mom was like there has to be something else. my dad was like it's now time. i think if dad hadn't intervened, my mom would have still been there when i graduated four years later. >> chelsea was an adult now, on her own. shielding her from controversy as hillary had done for 18 years would be much harder. >> how difficult is it for you to hear so many people harshly criticize your mother? >> well, it's just been something i've got i don't know accustomed to over my life.
