Martin Luther King III called Lewis an "American treasure."

"He gave a voice to the voiceless, and he reminded each of us that the most powerful nonviolent tool is the vote. Our hearts feel empty without our friend, but we find comfort knowing that he is free at last," the human rights advocate and son of civil rights leader Martin Luther King Jr. wrote on Twitter.

Rep. Don Beyer of Virginia compared Lewis's death to a light going out in the world.

"The grief of losing this great soul is beyond words. But we have been greatly blessed — our world is so much better for having had John Lewis in it," Beyer wrote.
