“Under the circumstances, further delay of Senator Graham’s testimony would substantially burden the overall delay in conducting the grand jury investigation. Further delay therefore creates a substantial risk of overall obstruction of the grand jury investigation, and therefore the Court finds that granting a stay would almost certainly cause material prejudice to the grand jury and its investigation. Accordingly, this factor weighs against Senator Graham and in favor of the grand jury,” Judge Leigh Martin May wrote Friday. U.S. Sen. Lindsey Graham, RS.C., addresses business leaders during a congressional conversation sponsored by the South Carolina Chamber of Commerce, Thursday, Aug. 18, 2022, in Columbia, SC (AP Photo/Meg Kinnard ) Meg Kinnard/AP Graham is scheduled to testify Tuesday, but there is still a motion for a stay. He had asked the judge to quash the subpoena requiring his appearance. Graham was subpoenaed last month as part of the Fulton County District Attorney’s criminal investigation into Trump’s efforts to overturn the Georgia election results. Fulton County District Attorney Fani Willis officially opened the investigation in February 2021, sparked in part by Trump’s phone call to Georgia Secretary of State Brad Raffensperger, in which he pleaded with him to “find 11,780 votes,” the exact number that Trump needed to win.
