OMB warns feds not to visit WikiLeaks

The memo argues viewing the classified documents on a non-secure computer would pose a security risk, despite the fact they are already publicly available on WikiLeaks. WikiLeaks has been forced to relocate its servers to Europe and set up mirror sites in the past week as authorities have closed in around the online whistleblower and its elusive founder Julian Assange.

"Federal employees or contractors shall not, while using computers or other devices (such as Blackberries or Smart Phones) that access the web on non-classified government systems, access documents that are marked classified (including classified documents publicly available on the WikiLeaks and other websites), as doing so risks that material still classified will be placed onto non-classified systems."

The memo also reminds feds that despite their publication, the documents are still considered classified and should only be accessed by those granted the proper authority by their agency head.

Additionally, a bipartisan group of senators unveiled a bill on Thursday aimed at stopping WikiLeaks by making it illegal to publish the names of U.S. military or intelligence sources.
