NBC senior correspondent Tom Brokaw says he is angry and hurt by “a torrent of unsubstantiated criticism” levelled against him by former NBC News correspondent Linda Vester, who alleged Brokaw made unwanted sexual advances toward her two decades ago. In the wake of the allegations, which Brokaw denies, more than 75 current and former female colleagues have signed a letter in support of Brokaw. NBC’s Kate Snow reports for TODAY.
