When it comes to politics, the First Lady certainly has a partisan agenda.

But Michelle Obama is also focusing on an effort with benefits across party lines: childhood obesity.

On "Let's Move! With the First Lady Michelle Obama" (TV One, 10 tonight), host Roland Martin talks with Mrs. Obama about her "Let's Move" movement, giving her a chance to explain the goals of the effort, her own healthy life evolution, and how you can get your kids to eat vegetables.

President Obama is often criticized for sounding wonky or professorial. Not so with Mrs. Obama. During the interview with Martin, she's plain spoken, conversational, and yet, informed.
