WASHINGTON — Chelsea Manning has been denied entry into Canada, according to a letter she recently posted to Twitter.

According to the letter Manning received from the Canadian government, she was “inadmissible on grounds of serious criminality for having been convicted of an offense outside Canada,” the letter reads.

The letter further describes Canada’s decision to bar Manning by comparing the offense she was convicted of in the U.S.

“If committed in Canada this offense would equate to an indictable offense, namely Treason described under section 46(2)(B) of the Criminal Code of Canada,” the letter states.

The story was first reported by The Intercept.

The letter is another setback for Manning, who was recently released from prison after former President Obama commuted her sentence.

Following public outcry, Harvard University recently rescinded its invitation for Manning to be a visiting fellow at the prestigious school. Former acting CIA Director Michael Morell resigned from Harvard as a result of the decision to invite Manning, according to a report from Military Times.

Former acting CIA director resigns from Harvard after Chelsea Manning named as visiting fellow Morell said he couldn't be part of an organization "that honors a convicted felon and leaker of classified information."

In 2013, Manning was convicted of espionage after handing over classified information that contained sensitive U.S. State Department cables covering the U.S. wars in Afghanistan and Iraq.

However, according to U.S. military investigations into the leak, U.S. officials found none of the leaks resulted in the deaths of any individuals or sources, according to a report from the Guardian.

Much of the material leaked by Manning was marked secret.

Manning was seeking entry into Canada at the Saint-Bernard-de-Lacolle point of entry located on the Vermont-Canada border, according to the letter.
