President Donald Trump’s eldest son, Donald Trump Jr, has tested positive for coronavirus.
The 42-year-old tested positive earlier this week and is currently isolating.
"Don tested positive at the start of the week and has been quarantining out at his cabin since the result," a spokesperson for Trump Jr said in a statement.
"He's been completely asymptomatic so far and is following all medically recommended COVID-19 guidelines."
Trump Jr is now part of a growing number of close presidential aides who have been infected with the virus, including Mr Trump himself.
On Friday, Rudy Giuliani’s son Andrew Giuliani, another White House aide, announced on Twitter he had tested positive.
Several of vice president Mike Pence’s aides have been infected, including his press secretary and chief of staff. Mr Pence himself has not been infected.
It comes as the United States logged another record number of new coronavirus cases in a day, as the country is in the grips of the third - and biggest yet - wave of the pandemic.
Data released by Johns Hopkins University on Friday showed that 187,833 infections were reported the day before.
The figure exceeds the last daily record by more than 10,000.
The US on Thursday logged 2015 deaths from COVID-19, according to the university's tracker, marking the first time since the beginning of May that the number of fatalities surpassed 2000.
Hospitalisations are also at record highs, straining health care systems.
The US, which has a population of about 330 million, has registered far more deaths and cases than any other country, recording more than 252,500 fatalities and 11.7 million infections since the start of the pandemic.
Multiple states are cracking down with new restrictions to curb the spread of the virus.
California Governor Gavin Newsom announced a month-long curfew, requiring nearly all of the state's 40 million residents to stay at home between 10pm and 5am.
Health authorities have urged people to stay home for Thanksgiving next week, a major US holiday in which families usually gather.
In promising news,.
US officials hope that 20 million people could be inoculated by the end of the year.
