Marcy Siegerson is the 69th Secretary of State and represents the State Department overall on Claire Underwood's Cabinet. She succeeded Catherine Durant in this role who was indisposed after Frank Underwood pushed her down the stairs at the White House. After Durant faked her own death, Siegerson attended her visitation along with Claire Underwood and President Viktor Petrov of Russia. Throughout the event, Petrov made clear the respect he had for Durant as a stateswoman and lack thereof for Siegerson as a newcomer, making negotiations difficult.
