Supporters of U.S. Army Pfc. Bradley Manning, who is suspected in one of the biggest security breaches in U.S. history, said Thursday that Web site WikiLeaks has fulfilled its pledge to aid in his defense by contributing $15,100, the Associated Press reported.

The Bradley Manning Support Network announced the gift.

Jeff Paterson of the affiliated group Courage to Resist, in Oakland, Calif., said the contribution brings the total raised for Manning’s defense to more than $100,000 but is still short of the $115,000 needed.

Manning is being held in maximum security at a Marine Corps base in Quantico, Va., awaiting a possible trial. He hasn’t commented on military charges that he illegally obtained more than 200,000 State Department cables and gave classified material to an unauthorized person.
