Harris was San Francisco’s district attorney from 2004 until she was elected California’s attorney general in 2010. She was the first woman and person of color to hold both positions, and currently is the state’s first African-American senator and the country’s first Indian-American senator.

5. Harris advocated for marriage equality

Harris refused to defend Proposition 8 in 2008, an amendment that would ban same-sex marriage. “I declined to defend Proposition 8 because it violates the Constitution.

9. Harris proposed tax reform that would create a refundable tax credit for workers

Harris has proposed tax reform that would create a refundable tax credit for all workers, peaking at $3,000 for single adults and $6,000 for married couples—meaning that taxpayers could collect cash even if they don’t actually owe any taxes, reported The National Review.
