Christine Pelosi: Whistleblowers are trying to alert us

Christine Pelosi, one of Nancy Pelosi's daughters, talks with Brian Stelter about the House Speaker's history-making week. She says Dems should "speak out" and "listen to the voices of the whistleblowers who are trying to tell us matters of urgent concern." She responds to right-wing attacks against her mother by saying, "I know that they wouldn't criticize Nancy Pelosi if she wasn't effective."
