The wholesale giant Costco has issued an order to remove all copies of Dinesh D'Souza's bestselling book, "America: Imagine the World Without Her," from the shelves of its stores nationwide, WND has confirmed.

The book, in this midterm election year, is a strong rebuttal of the progressive ideology behind President Obama's policies, which have been supported by Costco co-founder and director Jim Sinegal, a major Democrat donor and a speaker at the 2012 Democratic National Convention that nominated the president. A Washington Post political reporter has noted Obama's "romance" with the nation's second-largest retailer.

At Amazon.com, D'Souza's book, released June 2, is ranked No. 5 overall and No. 1 in Political Commentary and Opinion.

Costco has sold more than 3,600 copies of "America" nationwide, with about 700 copies sold last week as D'Souza's film by the same name opened at more than 1,000 movie theaters nationwide.

But Costco's book department issued the "pull order," requiring all Costco stores nationwide to remove the book, confirmed Scott Losse, an inventory control specialist in the book department at the Costco Wholesale corporate office in Issaquah, Washington, a suburb of Seattle.

The July 1 order required all copies to be removed by July 15.

Contacted for a reaction, D'Souza was surprised to learn of the Costco decision.

"If true, this would be very odd," D'Souza said.

"We're in the process of finding out what's happening. I look forward to getting to the bottom of this and continuing the strong relationship my publisher and I have always had with Costco and their millions of shoppers."

Most Costco stores WND contacted Monday had already pulled "America" from the shelves, with others scheduled to remove it with their regularly scheduled inventory changes Tuesday or Wednesday this week.

A few Costco stores told inquirers Monday they were "in luck," because a handful of books were still available and a few copies remained in the warehouse waiting to be returned. Staffers offered to put aside a book so it could be purchased before all copies were shipped back to the vendor.

WND contacted by telephone and email Costco's national book-buyer, Pennie Clark Ianniciello, at Costco's headquarters, but received no response to WND's questions regarding why D'Souza's book was being pulled from the shelves just as the companion movie was opening in theaters.

WND was unable to reach by phone or email Marji Ross, the president of Regnery, which published D'Souza's book.

Amazon readers have given "America" an average rating of 4.6 out of 5.

The Washington Examiner reported June 20 that the book sold 4,915 in the first week and 5,592 in the second week but mysteriously was kept off the New York Times bestseller list, where it would have ranked No. 8 and then No. 11 on the June 29 list.
