Transcript for Hillary Clinton at Odds With State Department Rules; Jeb Bush Makes First Visit to Iowa
Okay, thanks very much. Turning to politic, more fallout for Hillary Clinton over her use of a private e-mail account as secretary of state. And the first visit to Iowa for Jeb bush as he revs up his bid for the republican nomination. Jon Karl tracking both. This private e-mail account appears to be at odds with the state department's own rules even though it's not illegal. Reporter: That's right, George. The state department is now reviewing whether or not Mrs. Clinton violated a 2005 rule that was put in place to protect critical national security and diplomatic information. This rule said that employees are not allowed to send information, it is known as sensitive but unclassified, on private e-mail. That is not allowed except under emergency circumstances so they're going through her e-mails to see if she did any of that. That could potentially put at risk those e-mails falling into the wrong hands. Also, George, she was in clear violation of a rule that said that if employees use private e-mail, they must turn the e-mail over to the state department to be entered into government computers. As you know she didn't turn over e-mails until nearly two years after she left office. Investigations by at least two congressional committees at the same time. Jeb bush heading to Iowa for the first time. There's also been some scrutiny of his e-mail accounts and as an uphill fight. Reporter: The Iowa caucuses have been dominated by the conservative wing of the republican party. This is the wing of the republican party that is most skeptical of Jeb bush. Early polls in Iowa show that he's already well behind Scott walker, the governor of Wisconsin another likely candidate so this will be potentially skeptical crowd for him. Also, he's been spending so much time at fund-raisers, this is a chance for him to get out there and actually be with voters. We'll see how he does and be on the ground Sunday on "This week."
