President Barack Obama is calling the Secret Service prostitution scandal "a little distracting," but praises the agency for protecting him and his family.

Obama says in an interview on NBC's "Late Night with Jimmy Fallon" show that a "couple of knuckleheads shouldn't detract from what they do." Obama says, "What these guys were thinking, I don't know. That's why they're not there anymore."
