Barbara Walters walked away from an interview with Trayvon Martin shooter George Zimmerman after the former neighborhood watchman demanded at the last minute that, in return for the chat, ABC put him and his wife up in a hotel for a month, a source told Page Six. Walters flew down to Florida early yesterday and met with Zimmerman and his lawyer to discuss the possibility of a lengthy TV sitdown. Her interview would have taken place after he was done talking with Fox News’ Sean Hannity, a situation that already made the newswoman leery, we’re told, as she prefers to land exclusives. But we’re told that Walters was “appalled” by Zimmerman’s hotel demand, and told him the deal was off. An ABC News spokesman confirmed that Walters met with Zimmerman, but refused to confirm what he asked for. “She went down there with every intention of doing an interview, but Mr. Zimmerman made a demand at the last minute that we could not and would never agree to,” the rep said.
