Sarah Carpenter, a grandmother and school choice activist who had traveled six hours from Memphis to attend the event, confronted Warren backstage in a filmed exchange that went viral:
Carpenter: "I read that your children went to private schools."Warren: "No, my children went to public schools."
The clip went viral because Warren wasn't telling the truth. Corey DeAngelis, the director of school choice at Reason Foundation (the nonprofit that publishes this website), had discovered through online sleuthing that Warren's son Alex, now 43, had attended Kirby Hall, an elite private school in Austin, Texas. It subsequently came out that Alex had also attended the Haverford School, a tony all-boys academy outside Philadelphia.
