NEW YORK — If Ronan Farrow is exhausted, he certainly doesn't show it.

The crusading journalist, whose investigation into Harvey Weinstein's alleged sexual abuse for The New Yorker earned him a Pulitzer Prize last year, is razor-sharp and smiling as he walks into USA TODAY's New York offices on a late weekday afternoon, primed to talk about his new book "Catch and Kill," out Tuesday.

"I'm not getting a lot of sleep right now," admits Farrow, 31, who hastily chugs a full mug of hot coffee upon arrival. "But I'm proud of the reporting and I'm glad it's becoming public."

Part-memoir, part-thriller, "Catch and Kill" details Farrow's months-long struggle to report the Weinstein story for NBC, where he started as host of MSNBC's "Ronan Farrow Daily" in 2014, before becoming aninvestigative correspondent for "Today."

Farrow tells USA TODAY that he had multiple named accusers including Rose McGowan, and taped audio of Weinstein threatening model Ambra Gutierrez, when he brought his investigation to NBC executives. But according to him, they continually poked holes in his reporting and delayed running the piece, telling him it wasn't "newsworthy" and to "give it a rest" before killing the story altogether. (NBC News president Noah Oppenheim refuted Farrow's claims in a memo released Monday, writing that he had "no victims or witnesses on the record," including McGowan, who at the time, declined to identify Weinstein by name.)
