The Iraq invasion has emerged as a major campaign issue after Republican hopeful Jeb Bush walked back his claim he would have authorized the Iraq War. On Tuesday, Democratic hopeful Hillary Clinton was asked about her Senate vote in support of the Iraq invasion.

Hillary Clinton: “Look, I know that there have been a lot of questions about Iraq posed to candidates over the last weeks. I’ve made it very clear that I made a mistake, plain and simple. And I have written about it in my book. I’ve talked about it in the past. And, you know, what we now see is a very different and very dangerous situation. The United States is doing what it can, but ultimately this has to be a struggle that the Iraqi government and the Iraqi people are determined to win for themselves.”
