In the same interview, Warren, 62, admitted that into her 40s she was a Republican.
"I was a Republican because I thought that those were the people who best supported markets. I think that is not true anymore," Warren said. "I was a Republican at a time when I felt like there was a problem that the markets were under a lot more strain. It worried me whether or not the government played too activist a role."
