A federal magistrate judge in Virginia refused Thursday to free a former Army Green Beret who was arrested last week on a charge that he divulged U.S. military secrets to Russian intelligence agents. U.S. Magistrate Judge John Anderson agreed with federal prosecutors that Peter Rafael Dzibinski Debbins, 45, poses a risk to flee if he is released from custody before trial. Traxler said investigators had to corroborate details of a confession that he said Debbins gave when FBI agents questioned him last year.
