The US government has agreed to destroy all data obtained from a computer and other electronic devices seized from an outspoken advocate of a soldier accused of sending more than 700,000 classified documents to the website Wikileaks, the American Civil Liberties Union announced.
In a legal action, David House accused authorities of violating his constitutional rights when his computer was seized at a Chicago airport in 2010 while returning from abroad.
House is a founding member of The Bradley Manning Support Network, which raised money for Manning's legal defence.
"The seizure of David House's computer is a chilling example of the government's over-broad ability to conduct a search at the border that intrudes into a person's political beliefs and associations," John Reinstein, a lawyer for the liberties group, said.
A spokeswoman for the United States Department of Justice, which defended the government in the action, declined to comment on the settlement.
Manning has been charged with indirectly aiding the enemy by causing classified material to be published on Wikileaks. His espionage trial is due to start on Monday.
