The Supreme Court votes today on President Obama's Affordable Care Act--in a way. The justices will take a straw poll, telling each other which way they're leaning.

Are you feeling lucky today? If so, you're probably on your way to buy a Mega Millions ticket. Despite long odds of one in 176 million, lottery fever is running high, and Georgians this week were snapping up tickets at the rate of 150,000 per hour. Emory math professor Skip Garibaldi says the odds are comparable to those of getting both audited by the IRS and hit by lightning. The jackpot is at $540 million and could climb again before Friday night's drawing. UPDATE: Just before noon, the Georgia Lottery confirmed that the jackpot has risen to $64o million.

George Zimmerman says he was defending himself against Trayvon Martin's ambush when he shot the unarmed teen to death. But the video police released of the 28-year-old a half-hour after the killing shows no signs of injury. Former Florida U. S. Attorney Kendall Coffey says it almost destroys Zimmerman's credibility, explaining, "He may well be able to provide medical experts who say that the signs of the injuries that he claimed happened might not appear on a video. But in a court of law, this video tells you that his self-defense claim is simply not supportable."

Mrs. McClain says Lee called them personally to apologize and described him as "really kind...You could just tell he really felt bad about it. "
