State Rep. Brenda Gilmore leads the Nashville delegation this year in per diem , having taken $16,192 so far.

Other Nashville-based lawmakers, such as House Speaker Beth Harwell and Sen. Douglas Henry, give their per diem to charity or back to the government. Do you think Nashville-based legislators should keep their per diem? Why?
