I notice the New York Times article cleverly omits any direct quotes from the Bolton manuscript

I notice the New York Times article, despite its length, cleverly omits any direct quotes from the Bolton manuscript. Instead, it appears to rely on cherry-picked descriptions. Is the newspaper relying solely on sources or has it received a copy of the manuscript in whole or part? And as for the sources, who benefits from this? The public needs to know who’s leaking so we can make a judgment about their credibility. Who benefits? The publisher, Bolton, the Democrats, and the Trump-haters burrowed in at the White House.
