According to Entertainment Weekly, the final installment of the show, headlined Tea Leoni, will premiere next year.
The 10-episode conclusive run will tie up the storyline, Kelly Kahl, the network president, said.
We liked to be able to do this, to send show the off with a great deal of respect and celebration, Kahl added.
Led by Leoni's Elizabeth McCord, the US Secretary of State, the show also features Tim Daly, Sara Ramirez, Keith Carradine, Sebastian Arecelus, Patina Miller, Geoffrey Arend, Erich Bergen, Katherine Herzer, Wallis Currie-Wood, Evan Roae and Zeljko Ivanek.
The fifth installment ended with McCord preparing to resign from office to run for president.
