Transcript for Hillary Clinton Under Fire for Breaking State Department Rules
This is a busy day in a presidential campaign that hasn't officially begun although everybody knows it really has. Republican Jeb bush is in Iowa drumming up support and he's expected to make some hay of that e-mail scandal swirling around democrat Hillary Clinton who for her part will be giving a big speech in Florida tonight and ABC's David Wright is covering it all from Iowa. David, good morning to you. Reporter: Good morning, Dan. That e-mail scandal is shaking up to be the first new campaign issue for 2016 and it's one that reminds everyone of the downside of the Clinton brand. Her republican rival, her possible republican rivals seem to be enjoying every minute of it. That image of the globe-trotting elder stateswoman sunglasses and all is taking some serious hits today now that it's clear her use of the e-mail address on that blackberry broke the state department's rules. Was Clinton sending sensitive but unclassified information from her permanent e-mail? I just don't have details on that. I'm not going to speculate. We don't know. Reporter: We can't know because the only e-mails the state department has are the ones Clinton herself chose to hand over. On cable news one of president Obama's closest advisers would not rule out firing an employee caught using their personal e-mail account for government business. The president has a very firm policy that e-mails should be kept on government systems, he believes in transparency. Reporter: Here in Iowa former governor Jeb bush said security is also a concern and told an Iowa radio interviewer, it's a dangerous world. So high-level conversations need to take place behind a fire wall. It's a little baffling to be honest with you that that didn't come up in secretary Clinton's thought process. Reporter: A Clinton spokesperson insists there was nothing nefarious about what she did last night kicking off the annual Clinton global initiative conference, bill Clinton didn't mention the scandal at all. We have not heard the last of the e-mail scandal, it's safe to say. This weekend marks republican Jeb bush's 2016 Iowa debut. He'll be appearing with a dozen others at ag summit in des Moines.
