“I have taken every possible precaution and still contracted coronavirus,” Hayes, a Connecticut Democrat, said in a tweet. Hayes said she was asymptomatic except for breathing issues, which were being monitored.
At least 17 other members of the U.S. House of Representatives and Senate - nine Republicans and seven Democrats - have tested positive or are presumed to have had COVID-19.
In July, House Speaker Nancy Pelosi issued a mask mandate for the House floor after Representative Louie Gohmert, who often refused to wear a mask, tested positive. Elsewhere in the Capitol, mask wearing is encouraged for lawmakers, but not mandated.
Hayes on Twitter said that though mask-wearing, social distancing and cleaning precautions are taken in the House of Representatives, members of Congress are not regularly tested for COVID-19. Reporting by Daphne Psaledakis; Editing by Lisa Shumaker
