Witness | US v Pfc. Manning, Special Agent Calder Robertson, CCIU


United States v. Pfc. Manning was conducted in de facto secrecy. The public was not granted contemporaneous access to court filings or rulings during her trial. In addition to reporting on her trial, I transcribed the proceedings, reconstructed the censored appellate list, and un-redacted any publicly available documentation, in order to foster public comprehension of her unprecedented trial.

As a result of a lawsuit against the military judge and the Military District of Washington brought by the Center for Constitutional Rights, as well as my own FOIA requests and research, an official court record for US v. Pfc. Manning was released seven months after her trial. That record is not complete.

The official trial docket is published HERE and the entire collection of documents is text searchable at usvmanning.org.

*During the pretrial proceedings, court-martial and sentencing of Pfc. Manning, Chelsea requested to be identified as Bradley and addressed using the male pronoun. In a letter embargoed for August 22, 2013 Chelsea proclaimed that she is female and wished to be addressed from that moment forward as Chelsea E. Manning.

I also encourage you to visit Rainey Reitman’s account for the prosecution’s first questions to Special Agent Calder Robertson.

Robertson: I took word of investigating authorities.

Defense: So you don’t know if other individuals used the computers?

Robertson: No.

NB On August 25, 2012 I changed any spelling of the Special Agent’s name to consistently read Robertson, which is what I transcribed in my notebook in Court. Rainy Reitman had noted the name as Robinson, and Kevin Gosztola had noted Robertson.
