On the eve of Saturday's Nevada caucus, Ron Paul sits down with Piers Morgan for a revealing interview, during which the Republican from Texas shares his views on rape and abortion: "If it's an honest rape, that individual should go immediately to the emergency room, I would give them a shot of estrogen."

In an emotional one-hour sit down from Las Vegas, Paul says he feels life does begin at conception, but thinks basing his entire abortion position on a hypothetical situation can be difficult: "A person immediately after rape? Yes, it's a tough one. And I won't satisfy everybody there."

Tune in to "Piers Morgan Tonight" at 9pm ET/PT as the Republican race's oldest candidate goes into more detail on this controversial topic.
