Indianapolis (CNN) Sen. Kamala Harris rolled out two new policy proposals Friday aimed at closing the wealth gap among black Americans, focused on investing in higher education and entrepreneurship.

As the only graduate of a historically black college and university running in the 2020 presidential race, the Howard University alum proposed what her campaign calls "the next major planks in her black agenda."

Unveiling the policy at the National Urban League conference in Indianapolis, the California Democrat said she wants to invest $60 billion in science, technology, engineering and math education at historically black college and universities.
