Chelsea Manning tweeted Monday that she has been "permanently banned" from Canada under the Immigration and Refugee Protection Act.
According to the letter, the former Army solider has been denied entry to Canada "on grounds of serious criminality," citing her violation of the U.S. Espionage Act in which she was expected to serve 35 years in prison until former President Obama commuted her sentence. She was freed in May 2017 after serving seven years in prison.
Manning's release of thousands of secret documents in 2010 revealed prisoner abuse at Guantanamo Bay and shed light on a helicopter incident in Baghdad that led to the death of a photographer and driver working for the Reuters news agency.
