Hillary Clinton defended her record of email use on CBS’ “Face the Nation” on Sunday. It was reported last week that she had instructed staffers on how to send confidential information through unsecured channels. Clinton argued that there was often lots of unclassified information that could be sent unsecured. Clinton says that the staffer, who is now working on her campaign, never ended up sending out the information in question, which were a set of talking points for a phone call.
