Journalist and author Edward Klein is returning to Regnery Publishing to release Blood Feud, an account of the relationship between the Obamas and the Clintons. Set to be released on June 23, Blood Feud is said to examine the “deep” rivalry between the two political families.

A contributing editor at Vanity Fair and former foreign editor at Newsweek, Klein has published eight books including The Amateur: Barack Obama in the White House (2012), a New York Times bestseller, also published by Regnery. The publisher describes Blood Feud as an “expose” that “reveals never-before-reported stories” and is supported by “hundreds of interviews with insiders.”
