Twitter Wikileaks – Wikileaks said on Saturday the Twitter accounts of four supporters were subpoenaed as part of an investigation of spying on the website of denunciation led by an American jury secrecy.

Wikileaks, which began releasing 251,287 diplomatic cables from the United States in November, said he had reason to believe that Facebook and Google have also received court orders requesting details about users.

“Today, the existence of a secret U.S. government investigation into the espionage Wikileaks grand jury has been confirmed for the first time, a summons was brought into the public domain,” Wikileaks said in a statement.

Wikileaks said legal action brought by the micro-blogging site Twitter, “revealed that the U.S. State Department has asked private messages, contact information, IP addresses and personal details of Julian Assange and three others associated Wikileaks, in addition to Wikileaks? Own account, which has 634,071 followers.

He did not name the three other people, but the Icelandic Parliament Birgitta Jonsdottir said on his Twitter feed on U.S. authorities Saturday were asked to submit its Twitter account information and personal information.

“I come to this: Twitter has received judicial process requesting information on your Twitter account (from Wikileaks),” the champion of media freedom posted overnight.

“The demand for information is my tweet by the U.S. Department of Justice.” “The demand for information from twitter is also my personal information not only tweets,” she said.

Jonsdottir – a close associate of Wikileaks, which in September suggested Julian Assange retirement as spokesperson for the site because of the rape charges against him – said she considered the request of Justice Minister of Iceland.

He examines the case of requests for DoJ (Department of Justice) who want my contact twitter; it posted shortly after 1100 GMT on Saturday.

She said she had 10 days to stop the legal process and stressed the U.S. Department of Justice, not twitter, was to blame.

Wikileaks said on Saturday he was “opposed to the order of assignment and is taking steps to instruct lawyers in the United States.”

He urged Twitter to protect the private information of its users and stressed that other than Assange, the three people whose accounts had been subpoenaed had never worked for the site.

“Two have been instrumental in helping to Wikileaks Collateral Murder video – which showed a U.S. helicopter crew killed civilians they celebrate – in the public domain,” said Wikileaks.

The April 2010 release of the classified video, which shows U.S. Apache helicopter strikes in Baghdad that killed several people in 2007, has contributed to Wikileaks global spotlight.

The site has since angered the Pentagon in July 2010 by showing secret documents about the war in Afghanistan and then in October by a mass exodus of so-called “war in Iraq logs”.

Its release in November of diplomatic cables from the United States has embarrassed the governments around the world and led to numerous calls for Wikileaks to face a lawsuit.

The site has also suffered financial pressures when the credit card giants Visa and Mastercard said they would stop making gifts to the site.

“After trying to silence Wikileaks putting pressure on Paypal, Visa and Mastercard to cut off funding, the Government of the United States is now intrude into the privacy of certain supporters of Wikileaks most publicized,” Chief Julian Assange Wikileaks has said Saturday.

Assange, Australia 39-years, which is the public face of Wikileaks, is currently on bail in Britain to face extradition proceedings in Sweden on charges of S-EX-ual assault.
