Alabama AG Steve Marshall (R) touts the execution of death row inmate Kenneth Smith by nitrogen gas.

"As of last night, nitrogen epoxy as a means of execution is no longer an untested method. It is a proven one. It's the method that Kenny Smith ultimately chose, along with now 43 other death row inmates in our state. And thanks to the Fair Justice Act, which our administration passed during our first year in office, we are finally starting to see these cases move faster. It is my hope that one day, sooner rather than later, that the Alabama Attorney General won't have to stand up here and talk about how many decades some families had to wait before justice was served."
