The investigative blockbuster book Secret Empires by Government Accountability Institute President and Breitbart News Senior Editor-at-Large Peter Schweizer will debut at #1 on the New York Times combined print and e-book best-seller list, according to publishing industry sources.

Secret Empires, which is Schweizer’s fifth New York Times bestselling book, has caused a stir throughout official Washington with its newly unearthed revelations, including:

The author’s past investigative books have led to federal investigations, congressional resignations, or the launch of Capitol Hill ethics probes.

Schweizer’s 2015 book, Clinton Cash, broke the Uranium One scandal and sparked an FBI investigation into the Clinton Foundation.

In 2013, Schweizer released Extortion: How Politicians Extract Your Money, Buy Votes, and Line Their Own Pockets. CBS News’s 60 Minutes covered the book, which sparked the resignation of Rep. Rob Andrews (D-NJ).

In 2012, 60 Minutes covered Schweizer’s book Throw Them All Out, which uncovered insider trading by members of Congress and led to passage of the STOCK (Stop Trading on Congressional Knowledge) Act that banned lawmakers from using inside knowledge when making personal investments. The 60 Minutes story won the Joan Shorenstein Barone Award for excellence in Washington-based journalism.

Publishing giant Harper released Secret Empires: How the American Political Class Hides Corruption and Enriches Family and Friends on March 20.
