Allred had been traveling with 10 other members of Congress in Europe on a trip that included a meeting with Ukrainian President Volodymyr Zelenskyy. The 38-year-old Democrat said in a statement that he tested negative for the virus before boarding a flight back to Texas and again after landing, before testing positive Sunday.

Allred, a former Obama administration lawyer and NFL linebacker, said he is experiencing mild symptoms from the disease caused by the novel coronavirus. He said he is fully vaccinated and has received a booster shot.
