A rush of tickets sales have pushed the Mega Millions jackpot to over a half billion dollars. The jackpot has been boosed to $586 million, a jump from the earlier projection but still trailing a $656 million prize last year that was the largest in U.S. History.

Paula Otto, executive director of the Virginia Lottery and Mega Millions' lead director, said ticket sales are ahead of projections for Tuesday's drawing, increasing the likelihood that the record could fall by then. If the prize goes unclaimed for a 22nd consecutive drawing, the next one likely would shatter the record, set in March 2012, she said.
