Someone in the White House press unit is leaking like a sieve, and the group's leadership is seriously P.O.'ed about it. They need to bring in an experienced "mole hunter."
The usual plan is to provide a slightly different version of a story to each member and see which version gets leaked. Then the leaky individual is thanked for their service and transferred to a job where they can do little harm, perhaps in the General Services Administration or maybe at the Ag. Library.
