An article on Esquire magazine’s website, claiming that the publisher of Jerome Corsi’s new book about President Obama’s birth certificate is pulling it from bookstores, may have been written as a parody, but not everyone is laughing. The Esquire story, written by Mark Warren, spread across the Internet moments after being posted on the magazine’s website Wednesday morning. Esquire has said it was a joke and Warren told TheDC he has no regrets about posting it. “He is an execrable piece of ****,” Warren said of Corsi.
