A US military judge has reached a verdict in the trial of soldier Bradley Manning.

Colonel Denise Lind says she will announce her findings at (1100 AEST) on Tuesday). Manning faces a possible life sentence if convicted of the aiding the enemy for sending classified information to WikiLeaks. The 25-year-old also faces 20 other counts, including espionage, computer fraud and theft. He admits sending hundreds of thousands of classified documents and some battlefield video to the anti-secrecy website while working as an intelligence analyst in Iraq. In closing arguments last week, the defence portrayed Manning as a naive whistleblower who wanted to expose war crimes. Prosecutors call him an anarchist hacker and a traitor.
