The imprisoned Army whistleblower Chelsea Manning, formerly known as Bradley Manning, has formally filed a request for a presidential pardon. Manning was sentenced to 35 years in prison last month for leaking U.S. government and military files to WikiLeaks. In a letter to President Obama as part of the pardon bid, Manning writes: “The decisions that I made in 2010 were made out of a concern for my country and the world that we live in … Whenever we killed innocent civilians, instead of accepting responsibility for our conduct, we elected to hide behind the veil of national security and classified information in order to avoid any public accountability.”
