2020 candidates join marchers in Selma to commemorate "Bloody Sunday"
Some of the 2020 Democratic presidential candidates joined marchers in Selma, Alabama, who are commemorating the 55th anniversary of "Bloody Sunday" -- the violent confrontation that happened decades ago between African American demonstrators and dozens of state troopers. The incident sparked a major moment in the Civil Rights movement and paved the way for the Voting Rights Act.
