(WASHINGTON) — GOP Rep. Marjorie Taylor Greene on Friday will become the first member of Congress to publicly testify under oath about the events surrounding the Jan. 6 attack on the Capitol.

Monday night, a federal judge allowed a legal challenge by a group of Georgia voters to move forward as they seek to disqualify Greene from running for reelection, citing her alleged role in the Jan. 6, 2021, attack on the Capitol.

The voters argue a provision of the Constitution’s 14th Amendment known as the “disqualification clause” prevents Greene from holding federal office.

Passed shortly after the Civil War, the Disqualification Clause bars any person from holding federal office who has previously taken an oath to protect the Constitution — including a member of Congress — who has “engaged in insurrection” against the United States or “given aid or comfort” to its “enemies.”

An avid supporter of former President Donald Trump, Greene has denied any involvement in the attack and said she is appealing.

Judge Charles Beaudrot will preside over Friday’s hearing and witnesses will also be called to testify.

The time frame for the judge to render his decision on whether or not Greene should remain on the ballot is tight. Early voting for the Georgia primary begins May 2 and the primary itself is on May 17.

In an interview Tuesday with ABC News affiliate WTVC, Greene called the legal challenge a “scam.”

“All I did was what I’m legally and allowed to do by the Constitution as a member of Congress, and that was I objected to Joe Biden’s Electoral College votes from a few states,” Greene said.

Greene also said she was a “victim” on Jan. 6.

Mike Rasbury, one of the voters challenging Greene’s eligibility to run for reelection, said in a statement that Greene “took an oath of office to protect democracy from all enemies foreign and domestic … However, she has flippantly ignored this oath and, based on her role in the January 6 insurrection, is disqualified under Section 3 of the 14th Amendment to the U.S. Constitution from holding any future public office.”

Rasbury will be in the courtroom when Greene testifies.

Ron Fein, a lawyer representing the voters and legal director of Free Speech For People, told ABC News in an email that the Georgia “voters who filed this lawsuit have a right to have their challenge heard” and that he looks forward to questioning Greene under oath.

James Bopp, Greene’s attorney, told ABC News Tuesday that the challenge to Greene is “absurd” and that it shouldn’t be up to judges to decide who represents Georgia’s 14th Congressional District.

Bopp also represents GOP Rep. Madison Cawthorn, who is facing a similar challenge against his reelection from a group of voters in North Carolina.

Cawthorn’s lawsuit to dismiss the challenge to his reelection is set for oral arguments May 3 before the U.S. Court of Appeals for the Fourth Circuit in Richmond, Virginia.

Speaking on Fox News Monday night, Greene told host Tucker Carlson that Democrats are trying to keep her name off the ballot, maintaining she had nothing to do with the attack on the Capitol.

“I have to go to court on Friday and actually be questioned about something I’ve never been charged with and something I was completely against,” Greene said.

The challenges against Greene and Cawthorn are part of a larger legal effort to prevent anyone allegedly involved in the events surrounding Jan. 6 — or who supported it — from running for reelection.

Similar challenges are being brought against GOP Reps. Paul Gosar and Andy Biggs of Arizona and theoretically could be brought against Trump if he decides to run for office again in 2024.
