Homeland Security and Governmental Affairs Committee Chairman Joe Lieberman, (I-Conn.), doesn't think companies should be doing business with Wikileaks, and one company agrees.

Amazon.com has stopped hosting the Wikileaks website after staffers from the Senate Homeland Security and Governmental Affairs Committee asked about the company's relationship with the document leaking site. The federal government has called Wikileaks' posting of State Department and Pentagon documents a threat to national security.

"The company's decision to cut off Wikileaks now is the right decision and should set the standard for other companies Wikileaks is using to distribute its illegally seized material," Lieberman said in a statement. "I call on any other company or organization that is hosting Wikileaks to immediately terminate its relationship with them."
