Gabe gutierrez, thank you. Another story were covering. Hillary clinton ready to addre the scandal of her use of her personal email account while s was secretary of state. Andrea mitchell has more on that. Hillary clinton will hold a News Conference today, her fir in two years after intense pressure to clear up the controversy. Under fire for a second straig week, Hillary Clinton still isnt saying why she set up th private email system as secretary would you explain the email secretary clinton . Reporter she may be reluctant because of what happened in 1984. Under pressure she held a whit house News Conference about an Arkansas Land deal that led to more investigations. First, she wants todays focus to be womens rights as she continued to make history as potentially the first woman u. When women and girls have t opportunity to participate we can lift up not just ourselves, but our families, communities and even our countries. The email controversy was n part of the game plan and the white house acknowledged monda president obama did Exchange Emails with clinton when she w secretary of state, but said h didnt know she didnt also ha a government account. The president was not aware that this was a personal email server and that this was the email address that she was usi exclusively for all her business. Clintons longtime defender are firing back. Things are not going to change anything. It just gives people a reason get out of breath about a lot cockamamie, goofy stuff. Still 86 of democratic primary voters in the new poll support her. The emails show some vu with stories like this that bring an added level of scruti on her do is to remind people that shes a complicated candidate. When she does answer questions at todays News Conference, advisers say clintons likely explanation f using a private, mail account, with a complicated travel schedule it was convenient and it was not strictly prohibited by the rules and it was secure. Savannah . Thank you very much. Lets turn to chuck todd, moderator of meet the press. Good morning to you. My first question is why now . Are you surprised that secreta of state clinton decided shes got to do a News Conference wh the first approach was to say nothing and let this thing bur democrats are tired of havi to defend her without having more information to defend her thats the issue here. If it was just republican criticism or conservative medi criticism she would prefer not to be doing what shes doing, but shes getting criticism fr democrats and frankly, savanna anything short of some sort of if today is a deflection, throwback to how she handled things in the 90s and in the 07 campaign, democrats will want be happy. If she announces an action, i. E. , i am turning my server over to the government for the to have everything and it will at least quiet democratic the whole motive of this is to try to quiet this storm. In politics something seem catastrophic in the moment and later we say it wasnt such a big deal. In your mind, is this a story that has legs as we say in the News Business . Is this a story that will continue to dog her . Core democrats, they love h and cant wait to see her run for president. The reason it could dog her, though, come a general electio is that it feels familiar and this idea, president ial elections are about the future and not the past and if this scandal, if you want to call i that looks like more clintone 90s baggage and thats how i think they can hurt her. Chuck todd, thank you very much. Appreciate it. The u. S.
