Zuckerberg Gets Subpoena from Canadian Parliament Privacy Committee

A committee in Canada's Parliament voted unanimously to take the rare step of issuing a subpoena demanding appearances from Facebook CEO Mark Zuckerberg and COO Sheryl Sandberg. Bob Zimmer, chair of Canada's Standing Committee on Access to Information, Privacy and Ethics, said in a phone call with CBS News that the subpoena can only be enforced if the Facebook executives step foot on Canadian soil.
