Who is my U.S. representative in CO-04?

Captured 2026-07-11 00:10:16 UTC Model gemini-3.1-pro-preview
As of right now, your seat in Colorado's 4th Congressional District (CO-04) is **vacant**. 

Here is what is going on with your district:

*   **Why it is vacant:** Your previous representative, Republican **Ken Buck**, resigned from Congress on March 22, 2024, before the end of his term.
*   **When it will be filled:** A special election to fill the remainder of Ken Buck's term (which ends in January 2025) will be held on **June 25, 2024**. The candidates for this special election are Greg Lopez (R) and Trisha Calvarese (D). 
*   **The 2025 Term:** On that exact same day (June 25), there will also be a regular primary election to decide who will run in November for the *next* full term, which starts in January 2025. (This is the race that has made national news because Rep. Lauren Boebert, who currently represents CO-03, moved districts to run in the CO-04 primary).

**What to do if you need help right now:**
Even though you do not currently have a representative, the CO-04 congressional offices are still open and being managed by the Clerk of the House of Representatives. If you need help with federal agencies (like the VA, IRS, passports, or Medicare), the office staff can still assist you. 

You can find their contact information and office locations at **[buck.house.gov](https://buck.house.gov)** (the website remains active under the Office of the Fourth Congressional District of Colorado).
