Donald Trump Jr. has tested positive for the coronavirus, his spokesperson said.

President Donald Trump’s oldest son is asymptomatic, according to his spokesperson, and is in quarantine.

“Don tested positive at the start of the week and has been quarantining out at his cabin since the result,” the spokesperson said. “He’s been completely asymptomatic so far and is following all medically recommended COVID guidelines.”

Over the summer, CNN reported, Trump Jr.’s girlfriend, Kimberly Guilfoyle, tested positive for the virus while the couple campaigned for Trump across the country.
