Rev. Jesse Jackson, civil rights leader, Baptist minister and two-time Democratic presidential candidate, has died at age 84 in Chicago, his family announced. Jackson marched alongside Martin Luther King Jr., helped lead the civil rights movement in the 1960s, and later founded and headed the Rainbow/PUSH Coalition, a Chicago-based organization focused on voting rights, economic justice and social equity. He became a national political figure with influential presidential campaigns in 1984 and 1988. Jackson also undertook international missions that helped secure the release of Americans held abroad and received the Presidential Medal of Freedom.
