What office does Rosalind Thurman hold in Silo season 3?

Rosalind Thurman is a United States senator in Silo season 3.

Thurman appears in the season’s pre-Silo flashbacks as a senior American politician overseeing the congressional response to the supposed Iranian dirty-bomb attack in Washington, D.C. Her position gives her access to military and intelligence discussions, including the investigation involving Congressman Daniel Keene and journalist Helen Drew.

Her role is more consequential than a conventional legislative title suggests. Thurman becomes one of the principal figures behind the project that eventually produces the Silos, working with Per Stensen and other founders. The season gradually reframes her public authority as part of a much larger plan to preserve humanity through underground communities.

Viewers may confuse Thurman with Daniel Keene, who is explicitly described as a United States congressman. They are separate political figures: Daniel is the younger investigator trying to understand the Iran incident, while Thurman is the senator with institutional power and a direct role in the project’s creation.
