US Senator Lindsey Graham will fight a subpoena issued against him by a Georgia grand jury probing alleged illegal interference by former President Donald Trump to overturn results in the 2020 election, his legal team said Wednesday.

Graham won’t comply with the subpoena, his lawyer said, arguing Fulton County, where the grand jury is convened, is engaged in a “fishing expedition” and working with the House select committee investigating last year’s Capitol riot.

“Any information from an interview or deposition with Senator Graham would immediately be shared with the January 6 Committee,” said attorneys Bart Daniel and Matt Austin.

“Senator Graham plans to go to court, challenge the subpoena and expects to prevail,” the two lawyers also said.

Graham, a Trump loyalist, is one of several in Trump’s orbit subpoenaed. Others include members of the ex-president’s legal team, including Rudy Giuliani.
