It's "Big Block of Cheese" Day, which means that Leo sends grumbling staffers to meet with organizations who are not usually heard from at the White House. Toby, for instance, meets with World Bank protesters while C.J.'s assignment is the Cartographers for Social Equality. Meanwhile, a friend of Donna's (Jolie Jenkins) asks Sam to pursue a pardon for her grandfather, a White House staffer in the '40s who was convicted of perjury in a McCarthy-era spy case and died in prison.
