US Army supervisor knew of Manning's 'mental instability'
FORT MEADE, Maryland (AFP) - WikiLeaks' source Bradley Manning was allowed to handle secret intelligence even though he was plagued by "mental instability" and volatile behavior, his supervisor said on Tuesday.
Manning was convicted of espionage last month for passing a trove of secret documents to the anti-secrecy website WikiLeaks.
This week, his defence lawyer is arguing at sentencing hearings before a military judge that Manning should receive less than the maximum punishment for his offences.
The 25-year-old soldier is expected to read a statement as early as Wednesday and possibly take the stand to testify.
