(CNN) Patricia Arquette used her moment in the spotlight at the Screen Actors Guild Awards on Sunday to thank a person whose name is more often uttered on cable news than inside Hollywood events: Robert Mueller.

In her speech at the annual ceremony, Arquette thanked Mueller, the former director of the FBI and special counsel for the United States Department of Justice, and "everyone working to make sure we have sovereignty for the United States of America."
