The Cheaters, The Silver Star, Michael Phelps - S41.E10

Online gambling is illegal in the U.S., but it's a nearly impossible law to enforce. In this story, a group of men turn a dishonest cyber-poker game around and cheat to the tune of $20 million. In the second story tonight, Lara Logan reports on the second woman to ever win the Silver Star (the first being in World War II). Monica Brown wasn't even supposed to be there when she ended up saving two wounded men in battle.

Also tonight, Michael Phelps talks with CNN's Anderson Cooper. This 23 year old Olympic record breaker, now a marketing millionaire and still remarkably personable.
