In an appearance on CNN’s “Starting Point” on Monday to promote her call for J.P. Morgan Chase CEO Jamie Dimon to step down from the Federal Reserve Bank of New York., Warren doubled down and said she was proud of her disputed heritage.

“You know, I’m proud of my Native American heritage,” Warren said. “I’m proud of my family. It’s now the case that people have gone over my college records, my law school records, every job I’ve ever had to see that I got my work. I got my jobs because I do my work. I work hard. I’ve been a good teacher.”
