Under the offer, Manning would plead guilty to certain charges as violations of military regulations rather than as violations of federal espionage and computer security laws. The offenses would then carry maximum prison terms totaling 16 years rather than 72.
The pleas would include admissions that Manning sent WikiLeaks classified memos, Iraq and Afghanistan war logs, Guantanamo Bay prison records and a 2007 video clip of a U.S. helicopter crew gunning down 11 men later found to have included a Reuters news photographer and his driver.
The government could still prosecute Manning for all 22 counts he faces, including aiding the enemy. That offense carries a maximum penalty of life in prison.
