By Benjamin Clayton for Independent - There are difficult questions for Chelsea Manning to answer. As a visiting fellow – someone expected to speak publicly, answer questions, and be confronted by different opinions – everyone might have benefited. It is ironic that the most powerful most fear powerlessness. Enter Harvard University. This week, wobbled by pressure from the CIA and other institutions, the Harvard Kennedy School of Government rescinded its invitation to Chelsea Manning to become a visiting fellow at its Institute of Politics. With that, the most powerful university in the world silenced a twenty-nine-year-old transgender traitor-cum-hero. The facts of the case are these. In 2007, then-Bradley Manning enlisted in the Unites States Army. Six weeks later, she was almost discharged, partly due to the effects of being bullied by recruits. Amidst a national deficit of soldiers, however, the discharge was revoked and she was later trained in intelligence before being deployed to Iraq. Her first contact with WikiLeaks occurred in January 2010, and on 3 February she sent them roughly 490,000 documents. Over time, she sent more, including footage of a helicopter attack on Iraqi civilians in 2007. Manning was arrested in May 2010, convicted by court-martial in July 2013, and sentenced to thirty-five years confinement in August 2013; ultimately, this sentence was commuted by Barack Obama shortly before he left office.
