In the rallies and events she had attended prior to testing positive, Guilfoyle had reportedly not worn a mask. According to the report, chief of staff for the Trump Victory Finance Committee Sergio Gor said that she was sent into isolation the moment the test came back positive.She is "doing well, and will be retested to ensure the diagnosis is correct since she's asymptomatic, but as a precaution will cancel all upcoming events," according to Gor.Meanwhile, although the president's son tested negative for the virus, he will be self-isolating as a precaution due to Guilfoyle's results. Guilfoyle had reportedly not been in contact with the president recently prior to her test returning positive. The last time she had been near him was during the famous Tulsa rally, where the crowd was smaller than expected.
