that turned out to be kim brandt, medicare's director of program integrity. we went around with an f.b.i. agent and a woman from health and human services. they took us to storefront after storefront after storefront, billing $300,000 or $400,000 a month. and they were completely empty, nobody there. i mean, how do they get away with that? >> kim brandt: we're as frustrated by that as the law enforcement officials that you went out with. and in fact, our primary focus over the past years has been to tighten our enrollment standards to make it so it's much harder for people like that to be able to get in the program and to be able to commit that kind of fraud. >> kroft: look, i'm sure that you're aware of these problems. but it doesn't seem like you're doing a very good job. i don't mean you personally, but i mean, the... the government. this is still, like, a huge problem, and getting worse, right? >> brandt: well, it really does come down to the size and scope of the medicare program, and the resources that are dedicated to oversight and anti-fraud work. one
