Fort Meade , Maryland ( CNN ) -- Closing arguments are scheduled Thursday in the hearing for Pfc . Bradley Manning , the man accused of committing the biggest intelligence leak in U.S. history . On Wednesday , Manning 's defense attorney spent a brief 35 minutes questioning two witnesses before resting his case . Manning 's Article 32 hearing is part of the military 's process of determining whether he should face court martial . The first defense witness called was Sgt . Daniel Padgett who served with Manning in Iraq and witnessed one of several angry outbursts witnesses have described . Security Clearance blog : Bradley Manning and the need to share . Padgett was the senior enlisted man on the night shift in the intelligence office where Manning worked . He testified that in December 2009 , Manning was late for duty and they sat down in a conference room so Padgett could counsel him . Padgett said when they began talking , Manning was calm , but that he began to change . At some point , said Padgett , Manning grabbed the conference room table and turned the table over , knocking a computer and radio to the floor . Because there was a rifle in the room , Padgett testified that he did n't want Manning to get his hands on it , so `` I coaxed him away from that , put my hands on his shoulder and coaxed him away . '' At that point another soldier came in the room , subdued Manning , sat him down and Padgett continued counseling him , Padgett testified . When asked by Manning 's attorney David Coombs if Padgett remembered Master Sgt . Paul Adkins , the senior enlisted man in the unit , talking with him about the incident , Padgett said `` vaguely . '' Padgett testified that he did not discuss the outburst with the major who oversaw the intelligence analysis officers , the company 's first sergeant nor the company commander . Manning was not moved out of the intelligence office after the outburst and did not lose his security clearance as a result of the outburst . Coombs has argued that the Army should have known about Manning 's emotional issues and kept him away from classified materials . Manning is accused of stealing and leaking nearly three-quarters of a million classified documents from the State Department and the Defense Department to the WikiLeaks website , which published many of them . The leaks occurred while Manning was serving as an intelligence analyst in Iraq in 2009 and 2010 . Prosecution witnesses testified that Manning downloaded and leaked 400,000 DoD field reports from Iraq and 90,0000 similar documents from Afghanistan . There was also evidence presented that he downloaded and leaked more than 250,000 State Department cables . Coomb 's second witness , Capt . Barclay Keay , testified by phone about his time with Manning 's unit . For a short time in December 2009 , he was an officer in the intelligence analysis office where Manning worked . Keay said he often saw soldiers listening to music in the office where classified materials were analyzed . At first he thought it was not proper , but he was told it was `` an accepted practice '' that was `` tolerated because it helped soldiers be more productive . '' In news reports before the hearing , Manning is said to have bragged in a chat room that he was able to download materials onto a CD while pretending to listen to Lady Gaga . Keay told the hearing , `` I do feel like he wanted to be a good soldier . He did good analytical work . '' Even though he called only two , Coombs had requested 48 witnesses , 10 of whom were already on the prosecution witness list . The investigating officer overseeing the case granted those 10 and two other defense witnesses who were not on the prosecution list . He rejected other requested defense witnesses , including President Barack Obama and Secretary of State Hillary Clinton . Mark Zaid , a national security attorney , said the fact the defense called only two witnesses is not surprising . `` For one thing , an Article 32 ( hearing ) serves as an opportunity for the defense to obtain pre-trial discovery , and particularly information they do not know . Additionally , the likelihood of stopping charges from going forward is non-existent in this case so there is little value in telegraphing to the prosecution information the defense may possess but might not yet have revealed , '' said Zaid .
Manning 's defense calls only two witnesses . A witness tells the hearing about a Manning outburst . The hearing is part of a process of determining whether Manning should face court martial .
