The Supreme Court on Tuesday rejected appeals from three Republican U.S. House members who challenged fines for not wearing face coverings on the House floor in 2021.

The justices did not comment on leaving in place $500 fines issued in May 2021 to U.S. Reps. Marjorie Taylor Greene of Georgia, Thomas Massie of Kentucky and Ralph Norman of South Carolina.

The mask requirement was part of the House’s response to the COVID-19 pandemic, and the mandate remained in place even after the U.S. Centers for Disease Control and Prevention issued guidance noting that “fully vaccinated people can resume activities without wearing a mask or physically distancing.”

The lawmakers showed up on the House floor without masks, even posing for a selfie. The requirement was lifted in June 2021.
