WATCH: "West Wing" Cast Reunites For Harris/Walz Campaign

The West Wing is one of the most enduringly popular TV shows in history, giving viewers a behind-the-scenes glimpse of what it's like to work in the White House thanks to the fictitious Bartlet administration's two terms.  

In a perfect moment of kismet, the Aaron Sorkin-helmed series celebrated its 25th Anniversary at the real White House, with Martin "President Jed Bartlet" Sheen slipping back into his role quite easily along with several cast members. 

Sheen has been out on the campaign trail stumping for the Harris/Walz campaign, as have Bradley Whitford, Janelle Moloney, and Richard Schiff.

Former President Bartlet also brought his Deputy NSA Advisor with him to MSNBC.

Now the cast has come back together again to endorse Vice President Kamala Harris for President in a new ad created in partnership with The Lincoln Project

"We had the good fortune to work together on a television show called The West Wing," the cast wrote in a statement. "Our White House was a make-believe world. We dealt with real-life issues, from reproductive rights to national security, but when we went home at the end of the day, no one’s life was changed based on what happened in our fictional world."

The ad's powerful statements make it clear what's at stake in the very real election: The right kind of President reminds us that honor and dignity aren’t relics of the past but the foundation of our future.

The woman who will soon sit behind this desk will be the first in many ways.

She will lead America. To a new era. A proud era. A future where we will build as one nation.

A time of opportunity and prosperity for every American, every family.

Her name is Kamala Harris, and she will be our next President.
