Gunn Memorial Library in Washington will present a program with author, journalist, documentary filmmaker and multiple Peabody and Emmy Award-winning producer Chris Whipple Sept. 10 at 2 p.m.

Whipple will discuss and sign copies of his New York Times bestseller “The Gatekeepers: How the White House Chiefs of Staff Define Every Presidency.”

What do Dick Cheney and Rahm Emanuel have in common? Aside from polarizing personalities, both served as chief of staff to the president of the United States—as did Donald Rumsfeld, Leon Panetta, and a relative handful of others.

Through extensive, intimate interviews with all 17 living chiefs and two former presidents, Whipple pulls back the curtain on this unique fraternity.

Hickory Stick Bookstore will provide books for sale and signing.

For more information and RSVP, call the Wykeham Road library at 860-868-7586.
