Oklahoma Gov. Mary Fallin halted the execution of Richard Glossip at the last minute on Wednesday after prison officials tried to go forward with the wrong drugs, officials said. The stunning announcement came about an hour after the U.S. Supreme Court refused to stop the execution of Glossip, whose case drew a call for mercy from Pope Francis earlier in the day. The execution was rescheduled for Nov. 6. "Last minute questions were raised today about Oklahoma's execution protocol and the chemicals used for lethal injection," Fallin said in a statement.
