WASHINGTON (CNN) -- Lawyers for accused American Taliban fighter John Walker Lindh are asking the federal district judge handling his trial to subpoena an unidentified U.S. government agent to testify.

The agent, referred to as CS-1 (confidential source one), had refused a previous defense request to be interviewed by the attorneys.

Walker Lindh's defense team wants the agent to appear at a hearing scheduled for July 15 and at the trial.

Attorneys said agent CS-1 -- a CIA officer who was present with the late CIA agent Johnny "Mike" Spann during the prison uprising at Mazar-e Sharif, Afghanistan -- interviewed Walker Lindh.

Walker Lindh has pleaded not guilty to charges of conspiring to murder U.S. nationals, providing support and services to foreign terrorist organizations, and using firearms and destructive devices during crimes of violence.

Another Taliban fighter thought to be an American -- Yasser Esam Hamdi, 22 -- remains in U.S. military custody at Norfolk Naval Air Station in Virginia. Captured last year in the same prison uprising at Mazar-e Sharif, Hamdi was held with detainees at the U.S. Naval Base at Guantanamo Bay, Cuba, before it was determined he was born in the United States.

U.S. officials said they presume he is an American based on a birth certificate, but his citizenship status remains unclear.

A U.S. official said that no witnesses have emerged detailing Hamdi's actions.

U.S. interrogators have interviewed Hamdi, and sources said he maintains he was fighting against the Northern Alliance, not the United States.

Defense Secretary Donald Rumsfeld said on April 9 that no conclusions have been drawn on how to proceed in the Hamdi case.
