(CNN) - A judge on Thursday denied a request for President Barack Obama to testify at a court martial for a U.S. Army flight surgeon who refused to deploy to Afghanistan until he saw proof that Obama was born in the United States.
The judge, Army Col. Denise Lind, said any evidence or witnesses related to Obama's citizenship is irrelevant to the charges against Lt. Col. Terrence Lakin, who has 17 years of service in the U.S. military.
After failing to deploy with his unit in April, Lakin was charged with missing a movement, disobeying a lawful order and dereliction of duty.
