Republican Senator Scott Brown faced Democratic challenger Elizabeth Warren in the first debate of their closely watched Massachusetts Senate race Thursday. Brown began by attacking Elizabeth Warren for claiming on past documents that she was Native American. Warren defended herself, saying she had been told growing up in Oklahoma that her mother was part Delaware and part Cherokee. The candidates sparred over a number of issues during the hour-long debate, including Iran, women’s rights and economic policy.

Sen. Scott Brown: “The U.S. Chamber of Commerce said Professor Warren’s tax policies and her approach to them are the greatest threat to free enterprise. The NFIB said her tax policies would cut 700,000 jobs, 17,000 in Massachusetts. These are independent groups who have analyzed and pointed this out. I’m going to protect the hard-working men and women, the job creators, the people who are getting up in the middle of the night and creating jobs and protecting those interests.”

Jon Keller: “That was about 15 seconds. You take the same, and then we’re moving on.”

Elizabeth Warren: “Alright. So I think the point here is the Chamber of Commerce hasn’t talked about my particular proposals. What I’m talking about here is how Scott Brown has already voted, and also talking about what he said in his own voice last week he wanted to make crystal clear, and that is, he would let taxes go up for 98 percent of families in order to protect tax breaks for the top 2 percent. I wouldn’t do that.”
