2020 presidential race: Who is Tom Steyer?

Here are 8 things to know about him:

• Steyer was born June 27, 1957, in New York City.
• Steyer in 1979 earned his bachelor's degree from Yale University, where he was captain of the soccer team, according to a 2014 profile in Men's Journal. He went on to earn his MBA at Stanford University, according to the magazine.
• Steyer moved to San Francisco in 1986, where he started the hedge fund Farallon Capital Management LLC. He stepped down from the company in 2012, telling investors he planned to focus on giving back to the community full-time, including "continuing participation in our community bank, in encouraging the advanced energy economy and in specific public policy initiatives here in California," The Wall Street Journal reported in 2012.
