O’Brien has been working from home for a week, according to Bloomberg, and apparently contracted the virus at a family event.
“He has mild symptoms and has been self-isolating and working from a secure location off site. There is no risk of exposure to the President or the Vice President. The work of the National Security Council continues uninterrupted,” the White House said in a statement obtained by the Washington Post.
It would appear O’Brien’s infection marks the highest ranking Trump administration official to test positive for COVID-19.
