South Carolina Senator Lindsey Graham has filed a motion in federal court to fight a subpoena to testify if a Georgia special grand jury investigating alleged efforts to overturn the 2020 election results.

Graham was compelled to testify regarding calls he made to Georgia Secretary of State Brad Raffensperger and his staff in the weeks following the 2020 election. The South Carolina Republican says the subpoena is politically motivated and would set a dangerous precedent for members of Congress.

Graham has repeated that he never attempted to persuade Raffensperger to overturn Georgia’s election results.

Fox News reports:

“Senator Graham did not inject himself into Georgia’s electoral process, and never tried to alter the outcome of any election. The conversation was about absentee ballots and Georgia’s procedures,” Graham states in his motion to quash the subpoena, which was filed Tuesday in federal court in his home state of South Carolina.

According to Graham, the protections are absolute, and if members of congress are compelled to testify in small matters it would disrupt the operations of the federal government.

“What I’m trying to do is do my day job. If we open up county prosecutors being able to call every member of the Senate based on some investigation they think is good for the country, we’re opening Pandora’s Box,” Graham told Fox News in a statement.

Fulton County District Attorney Fani Willis sought to convene a special grand jury in order to “investigate any and all facts and circumstances relating directly or indirectly to possible attempts to disrupt the lawful administration of the 2020 elections in the State of Georgia.”
