Hall agreed to testify truthfully in all further proceedings in the case.
That's bad news for Trump and the other defendants.
One of the 19 defendants in a Georgia racketeering case against former President Donald J. Trump and his allies pleaded guilty on Friday to five misdemeanor charges, under a deal with prosecutors in which he would receive five years of probation.
The guilty plea of Scott Hall, 59, a Georgia bail bondsman, was a significant victory for Fulton County District Attorney Fani T. Willis, who secured an agreement from Mr. Hall to testify against other defendants. As of Friday afternoon, no other defendants have taken pleas; two of them, the lawyers Kenneth Chesebro and Sidney Powell, are scheduled to be tried together starting next month after demanding speedy trials.
Mr. Hall had been charged with racketeering, as well as six other felonies, for helping to carry out a data breach at the elections office in rural Coffee County, Ga., in January 2021. He and other Trump allies were apparently looking for evidence of ballot fraud after Mr. Trump lost the 2020 presidential election in Georgia.
