Representative Michele Bachmann of Minnesota has made a deal to publish her memoir, selling a book to Sentinel, a conservative imprint at Penguin Group USA, two people familiar with the negotiations said on Thursday. Ms. Bachmann, a Tea Party favorite who announced her presidential candidacy during the Republican debate on Monday, has been shopping her memoir for weeks, meeting with several New York publishers to discuss a possible deal. The book is tentatively expected to be released this fall. John Fund, a columnist for the Wall Street Journal, will assist with the writing of the book.
