The U.S. State Department has imposed an order barring employees from reading the leaked WikiLeaks cables. State Department staffers have been told not to read cables because they were classified and subject to security clearances. The State Department’s WikiLeaks censorship has even been extended to university students. An email to students at Columbia University’s School of International and Public Affairs says: “The documents released during the past few months through Wikileaks are still considered classified documents. [The State Department] recommends that you DO NOT post links to these documents nor make comments on social media sites such as Facebook or through Twitter. Engaging in these activities would call into question your ability to deal with confidential information, which is part of most positions with the federal government.”
