President Obama delivered a moving eulogy for Rev. Clementa Pinckney during his funeral service at TD Arena in Charleston, South Carolina, on Friday.
Toward the end of his speech, in which he referred to the state senator as a man who "believed in things not seen," the president surprisingly began singing "Amazing Grace."
Slowly, attendants and the choir joined in.
As the crowd picked up the song, Obama called out the name of each victim of the Emanuel African Methodist Episcopal Church shootings and said they "found that grace!"
The crowd responded to each: "Yes!"
"May grace now lead them home," he said.
