Bradley Manning, the 25-year old United States Army soldier, will be sentenced today for providing WikiLeaks with 750,00 pages of classified information. Manning could faces up to 90 years if convicted, CNN reports.

Manning was convicted of 20 of 22 charges in July by the presiding judge, Army Col. Denise Lind. Manning was not convicted of the most serious charge of aiding the enemy.

Manning was arrested in 2010 at the age of 22. The Potomac, Maryland native was stationed 40 miles east of Baghdad at Forward Operating Base Hammer at the time of his arrest.

Manning, an intelligence analyst, was exposed by an ex-hacker that he had been speaking with, according to a report by Wired in June 2010. In the course of their conversation it is reported that Manning took credit for leaking a video of a 2007 U.S. air strike in Baghdad that killed several civilians. WikiLeaks posted the video in April 2010.

Manning attorney has stated his client can be rehabilitated and should be spared a prison sentenced, CNN reports. Colonel Lind noted that Manning’s nearly three and a half years of detention will be considered before sentencing.

Since the time of Manning’s arrest, reports have focused on the conditions of his detainment. Before his conviction, Manning was detained U.S. Marine Brig in Quantico, Virginia after he was transferred from a military prison in Kuwait.

Reports from Salon.com in December 2010 revealed that Manning’s “sat alone in his cell” 23 hours a day.

Prosecutor, Capt. Joe Morrow, has asked for a minimum sentence of 60 years, according to CNN reports. Morrow believes “there may not have been a soldier in U.S. history who displayed such an extreme disregard”

The 750,000 page leak is perhaps the biggest leak of classified material in U.S. history, prosecutors say.Colonel Lind’s is expected to announce the extent of Manning’s sentence by 10 a.m., CNN reports.
