Oklahoma's two U.S. Senators are: 1. **James Lankford** (Republican) — serving since 2015 2. **Markwayne Mullin** (Republican) — serving since 2023 Both senators are Republicans, which reflects Oklahoma's status as a reliably conservative state. If you'd like, I can look up their current committee assignments, office contact information, or the latest news about their work. Would you like me to search for any up-to-date details?
