The statement comes after three House Republicans who had come in direct contact with Trump put themselves into self-quarantine after attending CPAC and coming in contact with the individual who tested positive for the virus. Reps. Doug Collins of Georgia, Matt Gaetz of Florida and Mark Meadows of North Carolina all directly interacted with Trump in the days after the February conference. Texas Sen. Ted Cruz, who was also at the conference, has also since placed himself into self-quarantine.

Trump made an appearance at a news briefing Monday evening led by Vice President Mike Pence along with other administration officials combating the outbreak. As Trump left the briefing, reporters peppered him with questions on whether he had been tested for the virus. He frowned and walked off in silence.

Pence said during the briefing that he had not been tested for the virus.

As of Monday night, more than 600 people have been found to be infected with the disease in the United States, with at least 26 deaths. Trump announced the administration would be looking at financial assistance to encourage workers to take time off if they feel ill.
