The National Peace Corps Association says it's looking for about 100,000 good volunteers.

They're people who served in the overseas development program at some time in its 50-year history but later lost touch with their former colleagues.

NPCA President Kevin Quigley says there's no complete list of the 200,000 Americans who volunteered for the program, in part because key records were lost during its early days.

"When the agency was in its infancy [in the early 1960s], a lot of systems for tracking former volunteers just didn't exist," Quigley says.

Mitt Romney is building momentum with wins in Iowa and New Hampshire. But he still faces criticism from fellow Republican rivals as the candidates turn toward South Carolina's primary.

Panelists discuss the Obama administration's latest immigration proposal that's meant to cut through bureaucracy — but critics call it 'back-door amnesty.'

The Glock is rapped about in hip-hop songs and carried by heroes in action films. It was once touted as the gun of the future, but also derided as a terrorist's best friend. Host Michel Martin and Paul Barrett, author of Glock, discuss how an obscure Austrian manufacturer of door hinges and knives ended up making America's top-selling handgun.
