The first lady said the Obamas have a special affinity for the agents assigned to protect them.

"People always ask what it is like to have Secret Service around," Mrs. Obama said. "It's like having family around. ... We have a fight among our family over who's getting which people.

"Sasha will come in, it's like, 'You took Scott!'" Mrs. Obama said. "Malia's like, 'You took Scott? That's not fair!' And then I'll say the same thing to Barack. It's like, 'Why did you get Beth?' It's dinner table conversation."

Mrs. Obama said a good relationship with the agents is important "when you're trying to live a normal life and raise a couple of girls in the White House."
