She said during a news conference at the United Nations last month that she used a personal account over a government one out of convenience. She deleted about 30,000 emails that she has described as personal in nature and has declined requests from congressional Republicans to turn over her server for an independent review.

“Through its unwillingness to address our biggest challenges in an honest way, the Obama administration has put us on a perilous course for both our short-term and our long-term futures,” Christie told the New Hampshire Institute of Politics at Saint Anselm College. “See, I think it’s time to tell the truth about what we need to do in order to solve our problems and put our country back on the path to greater prosperity.”

“I think it’s fair to say that as you look across the country the deck is still stacked in favor of those already at the top,” she said in a meeting with students and teachers at a community college in rural Monticello. “There’s something wrong with that.”
