The highly anticipated investigative bombshell book Profiles in Corruption: Abuse of Power by America’s Progressive Elite hit #1 on Amazon Saturday, despite the fact that the book’s official release is still over a week away.

When Axios and Breitbart News first reported about the book’s unveiling by publisher HarperCollins on Thursday, Profiles in Corruption was #822,128 on Amazon. Less than 48 hours later, the book zoomed to #1 across all book genres.

Very little is publicly known about the book’s contents. Government Accountability Institute President and Breitbart News senior contributor Peter Schweizer and his investigative team spent a year and a half researching it. A source close to the publisher said the book’s contents will “upend official Washington” and that Schweizer’s prior bombshell revelations about Hunter Biden were “just the tip of the iceberg.” The book is said to contain brand new evidence that five members of Joe Biden’s family—the “Biden Five”—scored “tens of millions of dollars” in taxpayer cash and guaranteed loans.

Mike Allen of Axios , who exclusively announced HarperCollins’ forthcoming release of Profiles in Corruption , reported that the book’s table of contents includes chapters on leading progressives, including:

Joe Biden

Eric Garcetti

Cory Booker

Elizabeth Warren

Sherrod Brown

Bernie Sanders

Amy Klobuchar

If Schweizer’s next book is anything like his four previous consecutive New York Times bestsellers, Washington will feel its shockwaves. Secret Empires exposed Joe and Hunter Biden’s Ukraine and China dealings, touching off a firestorm of coverage about Hunter Biden’s $83,000 a month work on behalf of Ukranian energy giant Burisma while Joe Biden led U.S.-Ukraine policy as vice president. Clinton Cash sparked an FBI investigation into the Clinton Foundation and uncovered the Uranium One scandal. Extortion led to lawmakers retiring. And Throw Them All Out pulled back the curtain on insider trading by members of Congress and led to the passage of the STOCK (Stop Trading on Congressional Knowledge) Act.
