The increasing involvement of Justice Clarence Thomas’ wife, Ginni Thomas, in the Jan. 6 House investigation is another blow to an already wounded U.S. Supreme Court and a potentially dangerous moment for the court’s senior associate justice.

The House committee investigating the 2021 assault on the Capitol reportedly is examining emails between Ginni Thomas and John Eastman, a former Justice Thomas clerk and a central figure in the attempt to change the results of the November 2020 presidential election. Earlier reports showed Ginni Thomas also engaged in email correspondence with former President Donald Trump’s chief of staff, Mark Meadows, and Arizona state legislators, urging them to fight the election results.
