Sen. Ron Johnson has tested positive for COVID-19, his office announced Saturday – making him the third senator to test positive in recent days.

Johnson returned to Washington on Sept. 29, having been in quarantine for two weeks after being exposed to someone who tested positive earlier in the month. He was exposed shortly after returning to the capital, his office said. He was then tested Friday, which came back positive.

Johnson is the third senator to test positive in two days, since it was announced that President Trump and first lady Melania Trump had tested positive for the virus early Friday. Trump was hospitalized at Walter Reed National Military Medical Center late Friday and has since been given a treatment of Remdesivir.
