An attendee of the conservative conference CPAC was diagnosed Saturday with coronavirus, said the conference organizer, American Conservative Union.
The attendee did not come in contact with President Trump or Vice President Pence, the ACU said.
The individual also did not attend any events in the main hall, the ACU said.
The ACU said it has been in contact with the state of Maryland Health Department and would "explicitly follow the guidance from government health experts."
CPAC is one of the largest conservative gatherings in the country and was attended by numerous White House officials and prominent Republicans.
