According to the US Department of Justice, Snowden publishes the book - with the Swedish title "In the Public Service" - without first submitting it for review with the intelligence services. As a result, he has violated the duty of confidentiality he entered into as a intelligence agent, the ministry believes. The same goes for speeches Snowden has made.
The United States will request all revenue that the book brings to Snowden, the department also announces.
Snowden is probably the world's best known whistleblower, in 2013 he leaked documents on US mass surveillance of the Internet and telephony. He lives in exile in Russia.
