President Donald Trump’s oldest son, Donald Trump Jr., tested positive for coronavirus earlier this week and is isolating, according to three people familiar with the matter.

A spokesman for Trump Jr. said in a statement he is asymptomatic for COVID-19, the disease caused by the virus.

Trump Jr. adds to the dozens of people associated with the president who have been infected by the virus, including Trump himself. On Friday, Rudy Giuliani’s son Andrew Giuliani, who is a White House aide, announced on Twitter he had tested positive. In addition, an aide to Vice President Mike Pence, Hannah MacInnis, tested positive earlier this month, according to two people familiar with the matter.
