Cookie Buckingham is the daughter of third-term United States Senator Buckingham who is in charge of assigning CIA task force positions. When Stan becomes frustrated when his years of service go unnoticed by Senator Buckingham in "School Lies", he decides to try to become a golf buddy as well. Unfortunately, Francine insists on sending Steve to a private school instead of Stan getting to join the golf club when Pearl Bailey High School is closed for asbestos removal. Stan is disappointed until he discovers that the Senator's daughter Cookie is a student at the same private school. Stan tries to make Steve attend the new school but he refuses so Stan is forced to disguise Roger as Steve. Stan is able to get his golf invitation with the Senator and is about to ask for a task force position when he learns that Roger sold the Senator's daughter to pay for a drug binge they went on together. Stan manages to locate and save the Senator's daughter, but over dinner, Cookie passes out in her food. Just as Stan is about to ask for a task force position, Francine calls to report Steve had been arrested for armed robbery. When the Senator points out that career is more important to him than family and ignores his daughter's plight, aside from having a maid shoot adrenaline into her heart, Stan decides to use his favor to ask the Senator to have his son bailed out.
Cookie is voiced by Azura Skye.
