Direct answer: A group of eight Democratic senators (plus one independent who caucuses with Democrats) broke with the party line to support a Republican-led deal aimed at ending the shutdown. Key names frequently cited include Catherine Cortez Masto (Nevada), Angus King (Maine, independent), Tim Kaine (Virginia), Jeanne Shaheen (New Hampshire), John Fetterman (Pennsylvania), and others, with several reports noting additional Democrats such as Dick Durbin (Illinois) among those who joined in the final move to reopen the government. The vote shifted the effort toward a temporary funding measure intended to resume government operations, though many Democrats criticized the move due to concerns about expiring health subsidies and broader policy concessions.
