Republican Rep. Marjorie Taylor Greene of Georgia has been fined $48,000 for not wearing a mask on the House floor, according to a letter from the House Sergeant at Arms.

Greene has been fined 20 times for not wearing a mask. After receiving an initial warning in May, Greene was fined $500 for her first offense, and $2,500 for each subsequent offense, which is in line with House rules.

Greene has appealed at least one of her fines, but it was upheld. The fines come from Greene’s salary.

The letter from the House Sergeant at Arms was first reported by The Hill.
