The City Council of Memphis, a majority black city that is the 25th largest in the US, wants to remove a statue of Confederate Gen. Nathan Bedford Forrest. But the Tennessee legislature requires a governor-appointed commission to approve all changes to military and historical monuments throughout the state. Last year, the commission denied the city’s request to remove the monument to Forrest, who made a living in the slave trade and led a massacre of black Union soldiers during the Civil War.
