The commissioner of the Food and Drug Administration (FDA) has entered self-quarantine after coming in contact with a person who has tested positive for COVID-19.
Hahn wrote a note to staff on Friday to alert them to the contact.
The person he came into contact with wasn’t identified.
He'll be in isolation for two weeks.
Hahn was scheduled to testify before a Senate panel on Tuesday, along with infectious disease expert Dr. Anthony Fauci and CDC Director Robert Redfield. The three officials are all part of the White House Coronavirus Task Force.
The White House has put into place guidelines including tracing contacts of people who test positive for the new illness, press secretary Kayleigh McEnany told reporters Friday.
Neither Pence nor President Donald Trump had recent contact with Miller, an administration official told reporters.
A member of the military who works on the White House campus, who has been described in some reports as one of Trump’s valets, also tested positive for COVID-19 in recent days.
Trump and Pence “have since tested negative for the virus and they remain in great health,” spokesman Hogan Gidley said in a statement.
Trump and Pence will be tested on a daily basis going forward, officials said. They were previously tested on a weekly basis.
People who come into contact with Trump will also be tested every day, Pence said.
No member of Trump’s cabinet has tested positive for the CCP virus, which originated in China last year.
Some close to the president have previously entered isolation after exposure to a person who later tested positive, including his daughter, Ivanka Trump.
