Attorney General Eric Holder spent almost three hours on Capitol Hill on Tuesday, getting a grilling from members of the Senate Judiciary Committee about a flawed gun-trafficking operation that let hundreds of guns flow across the Southwest border.

Budget cuts are showing up on the streets of another Midwestern city. In Rockford, Illinois, they're turning out the lights. The city is in the middle of removing 2,300 streetlights, all in an effort to save money. That's about 15 percent of all the lights in town.

Corina Curry has covered the story for the Rockford Register Star and joins us now. Welcome to the program, Corina.

GOP presidential candidate Herman Cain undertook his first serious interviews since the allegations by a Chicago woman on Monday of sexual misconduct when she was seeking help from Cain during a job hunt. NPR's Tamara Keith joins Robert Siegel to explain.

Robert talks to Eugene Volokh, an expert on compelled speech at the UCLA School of Law, about the status of graphic warning symbols and messages on packs of cigarettes.

"I can categorically say I have never acted inappropriately with anyone, period," Republican presidential candidate Herman Cain just told ABC News' Jonathan Karl on a live ABC/Yahoo webcast.

Responding to the latest accusation by a woman — Sharon Bialek of Chicago — who says he sexually harassed her in the late 1990s, Cain said the charge is "baseless, bogus and false" and that Bialek is lying.

The number of students taught in traditional district-run schools is shrinking fast. That's because parents in post-Hurricane Katrina can pick and choose from a smorgasbord of schools with different approaches and cultures.

By many measures, this educational marketplace has improved student achievement. But as this experiment moves ahead, it's led to questions about whether the district is truly open to the most challenging students.

An appeals court judge appointed by President Ronald Reagan just wrote an opinion affirming the constitutionality of the federal law overhauling health care.

That makes three appeals court decisions in favor of the law and one against, if you're keeping track.

As we reported at the end of October, 2005 YU55, an asteroid bigger than an aircraft carrier, is set to have a very close rendezvous with planet Earth. It'll be closer than the moon and today at 6:28 p.m. ET, it will make its closest approach.

Don't worry. NASA is confident it will miss us. Here's a video NASA put together that explains the trajectory and shows an animation:
