Jeff Shell's restructuring means Lack — who came under fire after Ronan Farrow's book "Catch and Kill" accused NBC News executives including Lack's right-hand man Noah Oppenheim of killing his Harvey Weinstein reporting — will leave at the end of the month, instead of after the 2020 presidential election as previously planned.

Lack, who has also been accused of downplaying an explosive rape allegation against former "Today" host Matt Lauer, will be replaced by Telemundo chief Cesar Conde, who will oversee NBC News, MSNBC and CNBC.

"There had been talk of management changes for a while," said a source close to NBC. "Andy is so past his prime. Between the Ronan debacle, the Lauer debacle and even before that the Megyn Kelly and Brian Williams debacles, it's no wonder he's out."
