Aaron Klein's exposé of Barack Obama's notorious connections with extremists and America-haters has skyrocketed to No. 1 on the non-fiction list at Amazon.com and is now No. 4 on the overall best-seller's list.

"The Manchurian President: Barack Obama's Ties to Communists, Socialists and Other Anti-American Extremists" is the result of two years of solid investigations into those within Obama's inner circle as well as the president's shadowy younger years.

With more than 800 citations, the brand-new, autographed title from WND senior reporter and WABC radio host Aaron Klein bills itself as the most exhaustive investigation ever performed into Obama's political background and radical ties. Klein's co-author is historian and researcher Brenda J. Elliott.
