 FACT: Congresswoman Frost refers to her "district" several times,  and nobody addresses her as Senator, which suggests she is a member  of the House of Representatives. (Senators do not have districts; it  is a statewide office.) In the scene in the file room, however, she  tells Captain Pringle about a filibuster she initiated to block a  bill. A filibuster is a parliamentary tactic that is only possible  under the rules of debate in the US Senate, not the House.
