TV Line is reporting that Sara Ramirez is stepping down as a series regular, but there's hope that she could return for a guest appearance to wrap up her character's storyline.
Ramirez has played Kat Sandoval on the political drama since the fourth season. She was drafted in to replace Bebe Neuwirth, who played Nadine Tolliver.
If you watch Madam Secretary online, you know that Kat had left the world of politics behind prior to Elizabeth managing to bring her back into it.
Ramirez is best known for her role on the ABC medical juggernaut Grey's Anatomy. She departed the series after over a decade in the role in 2016.
