The National Book Festival will feature not just one but two members of Congress for its 2014 gathering, which kicks off Saturday at the Walter E. Washington Convention Center in downtown D.C. — Reps. John Lewis, D-Ga., and James E. Clyburn, D-S.C.  

Lewis, who’s been on a tear the last year for his graphic novel “March: Book One,” a collaboration with his aide Andrew Aydin and artist Nate Powell about his formative years as a child leading to the civil rights icon’s political awakening, will discuss his work on Saturday from 12:45 p.m. to 1:30 p.m. as part of the Contemporary Life program. He’ll sign books available for purchase from 2 p.m. to 3 p.m.  

Clyburn will discuss his memoir, “Blessed Experiences: Genuinely Southern, Proudly Black” earlier on Saturday as part of the Contemporary Life program, from 10 a.m. to 10:45 a.m., and will sign books from 11:30 a.m. to 12:30 p.m.
