Lawyers for two Oklahoma death row inmates scheduled to die next week want the state attorney general's office to reveal more information about the drugs to be used in the executions.

Lawyers for Clayton Lockett and Charles Warner sent a letter Friday requesting that the office comply with a state Supreme Court ruling they say compels it to identify and verify the drugs, and prove they are unadulterated, uncontaminated, unexpired and legally obtained.

In Wednesday's ruling, the state's top court said a secrecy statute protects the identity of the source of execution drugs but "not the identity of the drug or drugs to be used in executions."

A spokeswoman for the attorney general said the letter is being reviewed.

The men are scheduled to be executed Tuesday.
