Detention hearing — Allen concedes detention
At a detention hearing in U.S. District Court for the District of Columbia, Allen appears in an orange prison jumpsuit before Magistrate Judge Moxila A. Upadhyaya. His federal public defender, Tezira Abe, tells the court "He's conceding detention at this time," reserving Allen's right to challenge detention later. The government's request to put on its evidence anyway is denied as inefficient given the concession.
