Reacting to a Newsweek story in which Martha Stewart again claims that her take on The Apprentice was supposed to supplant the original, Donald Trump urged the domestic diva to take responsibility for her "failed" effort. "Your performance was terrible in that the show lacked mood, temperament and just about everything else [needed] for success," Trump says in a missive to Stewart. "Between your daughter, with her one-word statements, your letter writing [to ejected players] and your totally unconvincing demeanor, it never had a chance." Stewart, in turn, calls Donald's letter "so mean-spirited and reckless that I almost can't believe [he] wrote it." Whoa, these two are arguing like Olympic speed skaters.
