LAS VEGAS - The family of billionaire casino mogul and GOP kingmaker Sheldon Adelson revealed that it bought the Las Vegas Review-Journal, ending a week of speculation and demands by staff, media watchdogs and politicians to know the identity of the new boss.

A statement in Thursday's issue follows the announcement last week that the paper was sold for a second time this year to an unidentified buyer and at a markup, prompting scrutiny about the lack of transparency.

The Adelsons say they held back because they didn't want an announcement to distract from Tuesday's Republican debate held at the Venetian, the casino-hotel on the Las Vegas Strip that is part of Adelson's empire. Adelson is a major GOP donor.
