Assange: EU Must Investigate WikiLeaks Block WikiLeaks founder Julian Assange has urged the European Union to reverse its decision not to launch an anti-trust probe of U.S. credit card companies after they blocked donations to the secret-spilling website. Visa and MasterCard were among half a dozen U.S. payment firms to start the financial blockade just after the group published some 250,000 secret State Department cables in December 2010. Assange says they imposed the blockade at the instigation of "right-wing extremists" in the U.S. Congress. He was speaking via videoconference form Ecuador's embassy in London, where he has been living since June to avoid being extradited to Sweden over sexual misconduct allegations. The EU last week issued an opinion that the block did not appear to have violated anti-trust rules. WikiLeaks is appealing the preliminary finding.
