President Biden tested positive for COVID-19 again on Sunday and remains in isolation after the White House detected a “rebound positivity” on Saturday.
The president’s doctor, Kevin O’Connor, said in a memorandum that the president continues to “feel well” and “will continue to conduct the business of the American people from the Executive Residence” while under self-quarantine.
Mr. Biden, 79, who emerged from five days of self-quarantine after testing negative for the virus on Tuesday, tested positive for the virus on Saturday after receiving four back-to-back negative tests.
