Lind gave prosecutors until Friday to respond and said she would rule next week.

Manning, who served as an intelligence analyst in Baghdad in 2009 and 2010, has acknowledged giving the classified materials to WikiLeaks. The group posted the video footage of the 2007 Apache helicopter attack as "Collateral Murder."

At a pretrial hearing, Manning said he wanted to provoke a public debate about U.S. military and foreign policy.

Lind found him not guilty Tuesday of aiding the enemy, the most serious charge against him, which by itself could have meant a life sentence.

But she found Manning guilty of 20 other charges, for which he faces the prospect of decades in prison.

The Oklahoma native lived with an aunt in Potomac and studied at Montgomery College before he enlisted in the Army in 2007. He has been detained since his arrest in Baghdad in 2010.
