DES MOINES, Iowa (AP) — The estimated Mega Millions jackpot has risen to $449 million, making it potentially the 7th largest lottery jackpot in the U.S. Lottery officials in Des Moines say if any ticket matches the balls drawn Tuesday, the jackpot will be the largest since a $448.4 million Powerball prize won by a New Jersey family May 7. The highest jackpot drawn in the country was a $1.6 billion Powerball jackpot won in January by players in three states.
