Watch Live: March on for Voting Rights rally in Washington, D.C.

Some 58 years after the Rev. Dr. Martin Luther King Jr. gave his "I Have a Dream" speech at the first March on Washington, his son, Martin Luther King III, and other activists and advocates will participate in the March on for Voting Rights in the nation's capital on Saturday. The subsequent rally in D.C. and other cities across the U.S. will call on the federal government to protect and expand voting rights.

People will gather for the Washington march at 8 a.m. ET. The march itself will start at 9:45 a.m. and will proceed past Black Lives Matter Plaza, the White House and the Washington Monument, before ending in a closing rally that will run from noon to 3 p.m. Approximately 50,000 people are expected to attend, CBS Washington, D.C., affiliate WUSA reports.
