Dylan Roof, who is accused of murdering nine black churchgoers last month in Charleston, South Carolina, has pleaded not guilty on more than 33 federal charges.
However, his lawyers entered a not guilty plea because the government has not decided whether to seek the death penalty.
Judge Bristow Marchant entered the not-guilty plea on all counts.
Dylann Roof, who is white, appeared in the courtroom shackled. He was silent except for a few “yes” responses to the judge’s inquiries.
The family members of victims of the June 17 attack also spoke briefly.
