what u.s. senators represent Chattanooga?
Chattanooga is located in Hamilton County, Tennessee, and therefore falls under the representation of Tennessee's senators in the United States Senate.
As of my last update in January 2022:
Marsha Blackburn served as one of Tennessee's senators. She is a Republican and assumed office in 2019.
Bill Hagerty was the other senator representing Tennessee at that time. He is also a Republican and took office in 2021.
These individuals may still hold their positions, but I recommend checking the most recent information or the current United States Senate website for any updates or changes in representation.
