The House committee investigating the Jan. 6 riot at the U.S. Capitol is in possession of a number of text messages in which former White House chief of staff Mark Meadows and Ginni Thomas, the wife of Supreme Court Justice Clarence Thomas, talk about keeping President Donald Trump in office, a person familiar with the investigation said.

Thomas and Meadows exchanged the messages came as Trump allies were discussing a legal challenge to the results of the 2020 election. The Supreme Court, in an unsigned opinion in December 2020, dismissed a challenge from Republican state attorneys general to overturn the results.

The text messages were in a trove of documents and messages that Meadows turned over to the Jan. 6 committee before he stopped cooperating with the investigation.
