Johnston said in an interview on CBS’ “The Early Show” to air Friday that he wishes that he hadn’t issued the apology to Palin.

“I don’t really regret anything,” Johnston said, who has appeared nude on the cover of Playgirl. “But the only thing I wish I wouldn’t have done is put out that apology ’cause it kind of makes me sound like a liar. And I’ve never lied about anything. So that’s probably the only thing. The rest of the stuff I can live with.”
