The commander of U.S. Forces Japan apologized and announced that all military personnel in Japan would have to adhere to a night curfew beginning today.

The move comes after two Navy sailors allegedly raped a woman in Okinawa. Like the case in 1995, when three servicemen raped a school girl, opposition to U.S. bases swelled after the arrests.

As Republican Rep. Joe Walsh of Illinois was courting controversy last night by saying during a debate that the "health of the mother" isn't a reason for an abortion anymore, out in Arizona a Democratic candidate for Senate was stepping in it by telling a male debate moderator that "you're prettier" than CNN's Candy Crowley.

For all the talk about "binders full of women," and what was said when after the events in Benghazi, Libya, Obama and Mitt Romney both made their cases. Now, they prepare for the third and final debate on Monday. We also bid farewell to former Pennsylvania Sen. Arlen Specter.

Thursday, the company tweeted that it's done so for the first time — blocking a neo-Nazi group's account in Germany. Today, Twitter withheld another account — this one in Britain, belonging to a right-wing member of the European Parliament who tweeted support for discrimination against gays. Government officials are investigating both cases.

President Obama and Governor Romney have discussed the middle class a great deal during the debates, but the candidates haven't spent nearly as much time talking about the poor. To get a read on the state of poverty in America, host Michel Martin talks with Irwin Redlener, of the Children's Health Fund and Timothy Noah, a columnist for The New Republic.

During a televised debate Thursday on Chicago's WTTW, Rep. Joe Walsh (R-Ill.) reiterated his opposition to abortion in any circumstance. It's similar to the Republican Party's national platform, which doesn't have any exceptions for abortion in the case of rape or incest.
