When Lack began his first tenure as president of NBC News, in the nineties, “it was a fundamental shift of, all of a sudden, a tolerance for abusive behavior, whether it was sexually harassing or it was just verbally abusive,” Linda Vester, who raised the first complaint about Brokaw, told me. “Degrading, humiliating talk, mainly to women. And that became the climate under Andy Lack. It was just—it was very stark.”
