Last week, President Donald Trump dined with Brazilian President Jair Bolsonaro and his communications secretary.
Fabio Wajngarten had posted photos on social media of the meeting at Trump’s Mar-a-Lago resort at the weekend.
Photos showed him standing next to Trump wearing a “Make Brazil Great Again” cap.
Vice President Mike Pence was next to Trump.
Since then, Wajngarten has tested positive for the coronavirus, or COVID-19.
He is now under quarantine at his home.
