The trial of Fort Hood shooter Nidal Hasan enters the jury selection phase Tuesday after almost four years of delays.

Army officers from across the United States will be flown to Fort Hood for possible inclusion in the jury that will decide if Major Nidal Hasan will face execution following a November 5, 2009 shooting on base that killed 13 and injured 32.

Potential jurors may face questioning from the suspect, who recently fired his attorneys after they refused to assist in his “defense of others” strategy and has opted to defend himself at trial. That could change, however, as former U.S. Attorney General Ramsey Clark meets with Hasan Monday about possibly taking up his defense. Ramsey served under Lyndon B. Johnson and has defended war criminals like Saddam Hussein and Slobodan Milosevic.

Testimony in the trail will begin August 6. If Hasan acts as his own counsel, he will be allowed to question and cross-examine witnesses in the case, including victims of his shooting rampage.
