In a blog posting, Manning's attorney David Coombs said, "Over the past few weeks, the defense has been preparing for the possibility of additional charges in this case. The decision to prefer charges is an individual one by PFC Manning's commander." Coombs adds that it will be up to the presiding officer in an Article 32 hearing to determine which charges should be referred to court martial.
Manning has yet to go through an Article 32 hearing, which is the military equivalent of a grand jury proceeding. That has been delayed pending the results of a review as to whether Manning is mentally competent to stand trial.
Manning is currently being confined at the brig at the Marine Corps Base in Quantico, Virginia. His supporters have argued he is kept under stressful conditions, allowed no contact with other prisoners.
Defense officials say Manning is being treated like any other maximum-security detainee -- he just happens to be the only such detainee at the facility, and if there were others, he would be allowed to have contact with them.
