Attorneys representing Republican South Carolina Sen. Lindsey Graham say that he intends to challenge the subpoena that he was issued by an Atlanta-area special grand jury investigating former President Donald Trump's attempts to overturn the 2020 election in Georgia.
"Senator Graham plans to go to court, challenge the subpoena, and expects to prevail," attorneys Bart Daniel and Matt Austin said in a statement on behalf of Graham.
Graham's attorneys also wrote that in their "conversations with Fulton County investigators," they have been informed that "Senator Graham is neither a subject nor target of the investigation, simply a witness."
"This is all politics. Fulton County is engaged in a fishing expedition and working in concert with the January 6 Committee in Washington. Any information from an interview or deposition with Senator Graham would immediately be shared with the January 6 Committee," Daniel and Austin wrote in the statement.
