Even though President Joe Biden's coronavirus test was negative, he will remain in isolation until his second negative test.
The president's physician, Kevin O'Connor, wrote in a memo that Biden tested negative Saturday. "The president continues to feel well," he wrote.
"In an abundance of caution, the president will continue his strict isolation measures pending a second negative test as previously announced," O'Connor said.
Biden has isolated inside the White House since last Saturday after testing positive for the coronavirus.
