A last-minute ticket-buying frenzy could make today's Mega Millions jackpot the biggest lottery prize in U.S. history, and odds are mounting for a winner just a week before Christmas, a game official said. The prize swelled to $586 million on Monday, with another spike in sales expected today before the drawing at 10 p.m. Chicago time, said Paula Otto, Virginia's lottery director, who heads the multi-state Mega Millions game.
