US Vice President Mike Pence is not in quarantine and has tested negative to COVID-19, his spokesman said, after a close aide was confirmed to have been infected.
Mr Pence would go to work at the White House on Monday, spokesman Devin O'Malley said in a statement following some US media reports that Mr Pence would be self-isolating.
"Vice President Pence will continue to follow the advice of the White House Medical Unit and is not in quarantine," O'Malley said.
"Vice President Pence has tested negative every single day and plans to be at the White House tomorrow."
Mr Pence's spokeswoman Katie Miller tested positive, it was revealed on Friday, while President Trump's valet also tested positive last week.
Top US infectious diseases expert Anthony Fauci - who has become the trusted face of the government's virus response - told CNN he would undergo a "modified quarantine" after testing negative and having not been in close proximity to Miller.
Robert Redfield, the director of the Centers for Disease Control and Prevention, and Stephen Hahn, the commissioner of the Food and Drug Administration, will also self-isolate.
President Donald Trump, 73, Mr Pence, 60, and many others at the White House are tested daily. But Mr Trump and Mr Pence often defy the medical experts' guidance about wearing protective masks.
The US, which has recorded 79,500 deaths in the coronavirus outbreak, has also suffered its steepest job losses in history, with 20.5 million jobs lost in April.
Last week US President Donald Trump announced plans to shut down the highly visible coronavirus task force, only to backtrack one day later.

Members of the group - which coordinates between medical institutes, political staff and state governors - gave daily press conferences meant to inform the nation on the latest status of the pandemic.
But they were often overtaken by Mr Trump's own freewheeling question-and-answer sessions, and the press conferences ended roughly two weeks ago.
