“I’ve been through a lot of ups and downs in this company since I’ve been here,” Ms. Maddow said. “It would be impossible for me to overstate the amount of consternation inside the building around this issue.”

Ms. Maddow also revealed that NBCUniversal, the network’s parent company, had agreed to release NBC News employees from contractual clauses that could prevent them from speaking openly about sexual harassment they may have experienced at the network.

Ms. Maddow interviewed Mr. Farrow on her show — itself a surprise booking considering her bosses have been at war with him since the publication of his new book, “Catch and Kill,” in which he asserts that NBC executives blocked his reporting on Mr. Weinstein’s brutal treatment of women.
