COLUMBIA, S.C. -- The South Carolina Senate has agreed to let authorities use the electric chair to execute condemned prisoners if the state lacks the drugs needed for lethal injections.

The Senate voted 26 to 12 Tuesday for the proposal, which faces one more procedural vote before going to the House.

Since 1995, it has been up to inmates to choose lethal injection or electrocution in the state, which held its last electrocution in 2008.

South Carolina's execution drugs expired in 2013 and the state has been unable to get more from pharmaceutical companies, which are worried about legal challenges, protests and bad publicity.

South Carolina hasn't carried out an execution since 2011, and some prosecutors haven't sought the death penalty because the state has no drugs for lethal injection.
