WORCESTER, Mass. - Jack Teixeira, the Massachusetts Air National Guardsman accused of leaking highly classified military documents, appeared in Worcester Federal Court on Thursday for a detention hearing to determine whether or not he'd be allowed out on bail. 

His attorneys argued he should be allowed to live at his father's house while awaiting trial, while the prosecution, headed by Assistant U.S. Attorney Nadine Pellegrini, believes Teixeira can't be trusted.

U.S. Magistrate Judge David Hennessy did not make a decision on Thursday, opting to take what he heard during Thursday's detention hearing under advisement. 

Prosecutors argued that given Teixeira's track record, it's hard to imagine he wouldn't try and use the classified information he knows to make himself of value to U.S. adversaries, or as Pellegrini put it, "The defendant uses what he can to get what he wants."

Pellegrini also referenced hundreds of internet searches the 21-year-old Teixeira had made about mass shootings, as well as a suspension his sophomore year of high school over violent and racist remarks. 

The defense, meanwhile, believes Teixeira can be trusted out on bail under the watchful eye of his father, who testified at Thursday's hearing. 

Defense attorney Brendan Kelley said that because Teixeira didn't run when the New York Times accused him of being responsible for the leak, and because he was allegedy found on his mother's front porch reading the Bible when officers arrived to arrest him, he's not a danger. 

Nichols College President Glenn Sulmasy, an expert on national security, believes both sides made their case well. He understands why Hennessy needs additional time to think things over. 

"Think about the damage that's been caused to the United States' reputation, to our relationship with other countries, these are all items that are taken into consideration by a federal judge in a situation like this," Sulmasy said. "But, I do think that the public defender did a good job as well, because they even caused the judge to think and pause and others to stop and say 'Well really, he's only 21, he's a young man, is he really a flight risk?"

Hennessy hasn't indicated how or when he will make a decision - it could be in writing, or there could be another hearing.
