Stewart's show a mistake for all, The Donald says

The bleat goes on in the Donald Trump-Martha Stewart battle.

Now it's The Donald returning fire.

In a biting letter to Stewart, delivered Tuesday, Trump wrote that her version of "The Apprentice" was "a mistake for everybody — especially NBC."

The real-estate mogul was responding to the domestic diva's sniping to Newsweek that "Martha Stewart: The Apprentice" floundered last fall — canceled after one cycle — because Trump would not take his competing show off the schedule.

Her show was supposed to be the only "Apprentice" and was meant to start out with her firing Trump on the air, she told Newsweek in its issue on newsstands now. She'd made similar comments in previous interviews.
