Her office said she would be tested again Friday. A pair of tests — a rapid test and a more sensitive laboratory test — found no trace of the coronavirus, her office said.

Harris is fully vaccinated, has received a booster COVID-19 vaccine dose and is regularly tested under White House COVID-19 protocols. She is to be tested again on Monday.

The aide also is fully vaccinated and boosted, and had tested negative earlier this week and every day during the prior week, Harris’ office said.
