Breaking an eight-day silence since he fled to Russia, National Security Agency leak source Edward Snowden blasted the Obama administration Monday evening in a statement released by the anti-secrecy organization WikiLeaks.

In the statement, Snowden accused the administration of using old tools of "political aggression" to intimidate other countries from which he is seeking asylum, while using his citizenship as a "weapon."

"The Obama administration is afraid of you. It is afraid of an informed, angry public demanding the constitutional government it was promised — and it should be," Snowden said in the statement.

The WikiLeaks statement followed a Reuters report on a letter Snowden wrote to the Ecuadorean government Monday, in which he said that the United States government is responsible for costing him his family and freedom to travel amid an investigation into his leaks.

"While the public has cried out support of my shining a light on this secret system of injustice, the Government of the United States of America responded with an extrajudicial man-hunt costing me my family, my freedom to travel, and my right to live peacefully without fear of illegal aggression," Snowden wrote in the letter to President Rafael Correa.

Snowden threatened to disclose more information about the NSA's surveillance programs in the letter if releasing the information would "serve the public interest."

Here's Snowden's full statement, from WikiLeaks:

One week ago I left Hong Kong after it became clear that my freedom and safety were under threat for revealing the truth. My continued liberty has been owed to the efforts of friends new and old, family, and others who I have never met and probably never will. I trusted them with my life and they returned that trust with a faith in me for which I will always be thankful.

On Thursday, President Obama declared before the world that he would not permit any diplomatic "wheeling and dealing" over my case. Yet now it is being reported that after promising not to do so, the President ordered his Vice President to pressure the leaders of nations from which I have requested protection to deny my asylum petitions.

This kind of deception from a world leader is not justice, and neither is the extralegal penalty of exile. These are the old, bad tools of political aggression. Their purpose is to frighten, not me, but those who would come after me.

For decades the United States of America have been one of the strongest defenders of the human right to seek asylum. Sadly, this right, laid out and voted for by the U.S. in Article 14 of the Universal Declaration of Human Rights, is now being rejected by the current government of my country. The Obama administration has now adopted the strategy of using citizenship as a weapon. Although I am convicted of nothing, it has unilaterally revoked my passport, leaving me a stateless person. Without any judicial order, the administration now seeks to stop me exercising a basic right. A right that belongs to everybody. The right to seek asylum.

In the end the Obama administration is not afraid of whistleblowers like me, Bradley Manning or Thomas Drake. We are stateless, imprisoned, or powerless. No, the Obama administration is afraid of you. It is afraid of an informed, angry public demanding the constitutional government it was promised — and it should be.

I am unbowed in my convictions and impressed at the efforts taken by so many.

And the full letter to Ecuador President Rafael Correa, via Reuters:

"There are few world leaders who would risk standing for the human rights of an individual against the most powerful government on earth, and the bravery of Ecuador and its people is an example to the world. I must express my deep respect for your principles and sincere thanks for your government’s action in considering my request for political asylum.

"The Government of the United States of America has built the world’s largest system of surveillance. This global system affects every human life touched by technology; recording, analyzing, and passing secret judgment over each member of the international public. It is a grave violation of our universal human rights when a political system perpetuates automatic, pervasive, and unwarranted spying against innocent people. In accordance with this belief, I revealed this program to my country and the world. While the public has cried out support of my shining a light on this secret system of injustice, the Government of the United States of America responded with an extrajudicial man-hunt costing me my family, my freedom to travel, and my right to live peacefully without fear of illegal aggression.

"As I face this persecution, there has been silence from governments afraid of the United States Government and their threats. Ecuador, however, rose to stand and defend the human right to seek asylum. The decisive action of your Consul in London, Fidel Narvaez, guaranteed my rights would be protected upon departing Hong Kong - I could never have risked travel without that. Now, as a result, and through the continued support of your government, I remain free and able to publish information that serves the public interest.

"No matter how many more days my life contains, I remain dedicated to the fight for justice in this unequal world. If any of those days ahead realize a contribution to the common good, the world will have the principles of Ecuador to thank.

"Please accept my gratitude on behalf of your government and the people of the Republic of Ecuador, as well as my great personal admiration of your commitment to doing what is right rather than what is rewarding.
