Mega Millions Jackpot Swells

The Mega Millions jackpot now stands at around $586 million,and lottery officials said it could go even higher, surpassing last year's record $656 million jackpot. No one won the $425 million prize on Friday night. And officials Saturday raised the amount to $550 million for Tuesday's drawing, the fourth-largest in U.S. history. Ticket sales are up by as much as 20 percent in states that reported their weekend numbers. Sales are expected to spike today. If there's no winner tonight, the jackpot will climb even higher for Friday's drawing.
