Hour 1
In his State of the Union speech, President Obama called for the repeal of the 1993 “don’t ask, don’t tell” policy. Last Tuesday, Admiral Mullen and Defense Secretary Gates presented the Pentagon’s proposal for ending the “don’t ask, don’t tell” policy to the Senate Armed Services Committee. Should gay men and lesbians be allowed to serve openly in the military? And is now the time to try to change the policy. This hour, we debate “don’t ask, don’t tell” with two military veterans, ALEXANDER NICHOLSON and BRIAN MAUE.

Hour 2
Americans are desperate to live forever. We spend millions each year trying to postpone the inevitable. But is any of it paying off? Journalist GREG CRITSER reports in this new book "Eternity Soup: Inside the Quest to End Aging," that by 2050 there will be over a million Americans over the age of 100. This hour, we’ll talk to Critser about the science and pseudo-science behind extending life – from hormone cocktails to Calorie Restriction Societies.

Hour 1
This week on the Weekly Political Round-up, we’ll discuss the Tea Party Convention, Obama's budget, the politics of "don't ask, don't tell" and much more. Our guests are Matthew Yglesias a fellow at the Center for American Progress, and Mary Kate Cary former White House speech writer for George H.W. Bush and a contributing editor for U.S. News and World Report.

Hour 2
Things are not going well for Toyota. The U.S. Department of Transportation recently announced that it will be looking into "uneven braking" problems in the Prius. The automotive giant has already recalled close over eight million cars because of sticking gas pedals. We’ll discuss what all this means for Toyota with automotive industry analyst Maryann Keller. Then we’ll take a look at some of the hot news cars headlining at the Philadelphia International Auto Show with automotive journalist Marty Padgett, including a review of the Chevy Volt and the Aston-Martin Rapide.

Hour 1
With the election of Scott Brown as U.S. senator from Massachusetts, Democrats lost their filibuster-proof majority. There’s a lot of debate at the moment about the filibuster – is it a useful tool or a political tactic to stall legislation? We’ll devote this hour of "Radio Times" to a conversation about the history and the use (and perhaps over-use) of the filibuster. Our guests are congressional scholar SARAH BINDER and DON RITCHIE, historian of the U.S. senate.

Hour 2
This hour we talk to the father and son owners of Miller Racing Group, about what it is like to be an African American team in a still predominately white sport. Leonard W. Miller was the first black auto racing team owner to enter the Indy 500 over thirty years ago. His son Leonard T. Miller has written a book about their experiences breaking through the color barrier of NASCAR called "Racing While Black: How an African-American Stock Car Team Made its Mark on NASCAR."

Hour 1
Former Comptroller General of the United States, DAVID M. WALKER explains in his new book, “Comeback America” how he warned the Clinton and G.W. Bush administrations that America faced a growing fiscal imbalance. He’ll talk to Marty about how his projections played out and how the Obama Administration is handling the current economic crisis.

Hour 2
Author HOLLY PAYNE was struck and grievously wounded by a drunk driver in 1994, and was unable to walk for nearly a year. Through hard work and determination, she learned to walk again, and has competed in many triathlons since. But one of her greatest challenges came when the drunk driver wrote to her and asked for her forgiveness. Instead of the letter he requested, she wrote a book, "Kingdom of Simplicity." Holly, a native of Lancaster County, PA, who now lives in California, was inspired by the Amish practice of forgiveness, most notably on display following the Oct. 2, 2006 shooting of five Amish girls in a one-room schoolhouse. Her third novel, "Kingdom of Simplicity," tells the story of a young man who finds himself unable to forgive the driver who killed five of his sisters, and confronts his culture and his past during the Amish tradition of rumspringa.
