Watch: Funeral Underway For Civil Rights Icon John Lewis

The funeral for Rep. John Lewis, the civil rights icon who was widely revered by his peers as “the conscious of the Congress,” will be held in Atlanta on Thursday at Ebenezer Baptist Church, where Martin Luther King Jr. served as co-pastor.

Days of ceremonies have honored the longtime congressman in Georgia, his home state Alabama and Washington, D.C. where he represented Atlanta and some of its suburbs for more than 30 years.

He died at the age of 80 on July 17, after battling pancreatic cancer.

Three former presidents — Barack Obama, George W. Bush and Bill Clinton — are expected to speak at his service, which is scheduled to begin at 11 a.m.
