United States President, Joe Biden, has again tested positive for COVID-19.

The presidential physician, Dr. Kevin O’Connor, in a statement, said Biden tested positive for COVID-19 on Saturday morning.

O’Connor said the President tested negative on Tuesday evening, Wednesday morning, Thursday morning, and Friday morning before testing positive in the early hours of Saturday.

“However, given his positive antigen test, he will reinitiate strict isolation procedures,” the doctor noted.

President Biden ceased isolating on Wednesday after testing negative on successive antigen tests, celebrating his return in remarks from the White House Rose Garden.

Biden’s physician said the President is not experiencing any symptoms but that he will isolate at the White House.

The White House, on Saturday, said the President canceled plans to travel to his home in Delaware on Sunday and to Michigan, where he was expected on Tuesday to tout the recently passed bill aimed at boosting United States semiconductor production.

“Folks, today I tested positive for COVID again.

“This happens with a small minority of folks. I’ve got no symptoms but I am going to isolate for the safety of everyone around me. I’m still at work, and will be back on the road soon,” President Biden wrote on Twitter.

The 79-year-old President first tested positive last Thursday.

According to his doctor, Biden, during his first bout with the disease, experienced mild symptoms, including runny nose, fatigue, high temperature, and a cough.

The second positive test, however, came just three days after O’Connor said Biden had tested negative for the disease and no longer needed to isolate, which he had been doing since receiving a first positive result on July 21.
