Rep. Ayanna Pressley announced Wednesday that her husband, Conan Harris, has tested positive for COVID-19. Harris, Pressley and some members of Pressley's staff are isolating as a result of the test, according to a statement.

Harris had accompanied Pressley to Washington, D.C., for her swearing in and was with her throughout the day on Jan. 6, when members of Congress had to shelter together in close quarters as a mob of pro-Trump extremists attacked the U.S. Capitol. The Democratic congresswoman from Massachusetts laid the blame for her husband's illness at the feet of some of her Republican colleagues who refused to wear masks in the secure shelter locations.

"Their arrogant disregard for the lives of others is infuriating, but not surprising, and we are seeing the consequences of it daily, as several of my colleagues — and now my husband — test positive for COVID-19," Pressley said in a statement.

A video published by Punchbowl News showed a small group of Republicans members at the secure location on Jan. 6 decline masks after being offered them. At least three Democratic members of Congress who were in the secure location with them have since tested positive for COVID-19.

"The second I realized our 'safe room' from the violent white supremacist mob included treasonous, white supremacist, anti masker Members of Congress who incited the mob in the first place, I exited," Pressley tweeted Tuesday afternoon, prior to announcing her husband's diagnosis. "Furious that more of my colleagues by the day are testing positive."

Harris' test results came Tuesday evening, and he has mild symptoms, according to Pressley's office.
