Mark Walberg, host of Fox's Moment of Truth, has defended the lie-detector show against charges that it has wrecked the marriages of contestants and exploited people willing to air their dirty laundry for cash. Today's (Thursday) New York Daily News quoted Walberg as saying, "No family gets wrecked unless they're wrecking it anyway. And of all the people that have been on the show, only one couple that I know of that was married has decided to separate. And they were already on the rocks well before they got to us, by their own admission." New episodes of the show are due to begin airing on May 27.
