Conservative activist Virginia “Ginni” Thomas, the wife of Supreme Court Justice Clarence Thomas, appeared on Thursday for a voluntary interview with the House panel investigating the Jan. 6 insurrection.

The committee has for months sought an interview with Thomas in an effort to know more about her role in trying to help former President Donald Trump overturn his election defeat. She texted with White House chief of staff Mark Meadows and contacted lawmakers in Arizona and Wisconsin in the weeks after the election.

Thomas’ appearance on Capitol Hill was confirmed by two people familiar with the committee’s work who were not authorized to discuss it publicly.

She did not answer questions when she arrived for the interview or later when she briefly left for a break. But Thomas did tell reporters she was looking forward to answering questions from the members of the committee.

The testimony from Thomas — known as Ginni — was one of the remaining items for the panel as it eyes the completion of its work. The panel has already interviewed more than 1,000 witnesses and shown some of that video testimony in its eight hearings over the summer.

Thomas’ attorney, Mark Paoletta, said last week that Thomas had agreed to meet with the panel and is “eager to answer the committee’s questions to clear up any misconceptions about her work relating to the 2020 election.”

The extent of her involvement in the Capitol attack is unclear. In the days after The Associated Press and other news organizations called the presidential election for Biden, Thomas emailed two lawmakers in Arizona to urge them to choose “a clean slate of Electors” and “stand strong in the face of political and media pressure.”
