Kim said Ullah picked his target and timed his attack in order to "maximize human casualties."The bomb, however, did not fully explode".
Akayed Ullah, 27, faces charges that include supporting a foreign terrorist organization, using a weapon of mass destruction and carrying out a terrorist attack against a mass transit system, according to an indictment filed in federal court in Manhattan.
Ullah began to self-radicalize three years ago, authorities said, but law enforcement said he wasn't on their radar before the subway attack.
Ullah, a Bangladeshi immigrant, was the most severely injured person from the attack in the bombing of a heavily-trafficked underground walkway connecting the Port Authority bus terminal with the subway.
During a search of his Brooklyn apartment investigators recovered a passport with a handwritten note reading: "O America, die in your rage", as well as metal pipes, screws similar to those found at the explosion site, and wires, the complaint said.
Addressing reporters today, Ullah's attorney Amy Gallicchio emphasized the importance of due process.
The indictment was announced by the US Attorney's Office for the Southern District of NY. U.S. Magistrate Judge Katherine Parker is pictured at left on the bench beside the video monitor.
Republicans quickly seized upon Ullah's immigration status in the aftermath of his arrest. He faces life in prison if convicted.
When Manhattan Federal Judge Richard Sullivan asked Ullah his plea, Ullah replied, "At this moment, not guilty". President Donald Trump called for further restrictions to the F-4 program that allowed Bangladesh-born Ullah to obtain a USA visa, fueling the myth of an immigrant crime wave. Turner estimated that if the case went to trial, it would likely take one to two weeks.
