The forthcoming bombshell investigative book Profiles in Corruption: Abuse of Power by America’s Progressive Elite contains 1,126 endnotes totaling 83 pages of source material, Breitbart News has learned.

In addition, the book contains no unnamed sources. Instead, it is based on hard evidence and documents, including: foreign and domestic corporate and legal records, tax liens, lobbyist disclosures, property records, White House visitor logs, federal bankruptcies, and federal criminal trial records.

Publishing giant HarperCollins has kept Profiles in Corruption under a strict embargo. The book will reportedly expose how five members of Joe Biden’s family—the “Biden Five”—scored “tens of millions of dollars” in taxpayer money and guaranteed loans. In addition, the book is said to contain never-before-reported bombshell revelations about Bernie Sanders, Elizabeth Warren, Kamala Harris, Amy Klobuchar, Cory Booker, Sherrod Brown, and Eric Garcetti.

Last week Amazon named the book its “most anticipated” nonfiction book based on pre-sale volume. Ten days before the book’s January 21 release, it had already hit #1 on Amazon across all book genres.

The book’s writer, Government Accountability Institute President and Breitbart News senior contributor Peter Schweizer, is a five-time New York Times bestseller author who penned Clinton Cash and Secret Empires. According to Axios, Schweizer and his GAI team of investigators spent a year and a half researching Profiles in Corruption: Abuse of Power by America’s Progressive Elite.

Sean Hannity will kick off the book’s official launch on Monday.
