Unfortunately, TN does not appear to be a state that allows the recall of Senators.

"Eighteen states have recall provisions. Alaska, Arizona, California, Colorado,
Georgia, Idaho, Kansas, Louisiana, Michigan, Minnesota, Montana, Nevada, New Jersey,
North Dakota, Oregon, Rhode Island, Washington, and Wisconsin all have recall of some
kind available to their voters. Only seven of these states require any grounds."
