President Trump leaks White House tidbits to members of the media himself, despite launching repeated attacks on the press for pedaling "fake news," according to a forthcoming book.

“The president himself leaked to reporters as well, his aides believed,” Fox News host Howard Kurtz writes in his book about the Trump administration, "Media Madness: Donald Trump, the Press, and the War Over the Truth."

“And sometimes it was inadvertent: Trump would talk to so many friends and acquaintances that key information would quickly reach journalists,” Kurtz continues in an excerpt published by the Washington Post Sunday.

Trump's admissions contrast with Attorney General Jeff Sessions' crackdown on illegal leaks emanating from the Justice Department and the FBI announced in August.

In another example from "Media Madness," Kurtz recounts how Trump regretted asking former White House press secretary Sean Spicer to dispute the size of the crowd at his inauguration in January 2017.

Kurtz also reveals former White House chief strategist and ex-Breitbart News Chairman Steve Bannon once told Ivanka Trump, first daughter and adviser to her father, that she was "just another staffer who doesn’t know what [she's] doing.”

Kurtz's book corroborates with a description of West Wing disorder printed in Michael Wolff's Fire and Fury: Inside the Trump White House earlier this year.

"Media Madness" is set to be released on Jan. 29.
