The U.S. elected its 45th president on Nov. 8.
After two years of controversy over the state's execution procedures, Oklahoma voters issued a strong show of support for the death penalty on Tuesday.
State Question 776 passed with 66% of voters in support of the measure. It amends the state constitution to give state lawmakers more power to change the state's execution methods if those execution methods are ruled invalid.
Critics of the measure said it did little to change the legislature's existing powers.
The future of the death penalty had been in doubt in Oklahoma since the botched 2014 execution of Clayton Lockett, which led to intense scrutiny into the state's procedures.
