Three NBC staffers have slapped the network with an $800 million lawsuit, claiming racial and sexual harrassment, the New York Post reports. One of the plaintiffs, former Today show employee Gilbert Muro, says that he overheard a senior news director make racist remarks about then co-host Bryant Gumbel. Muro then moved to Late Night With Conan O'Brien, where he says sexual harassment was rampant. NBC is denying the charges.
