On Tuesday, former presidential candidate Hillary Clinton and White House Press Secretary Jen Psaki announced on Twitter that they tested positive for COVID-19.

That means Psaki will not be on President Joe Biden’s trip to Europe, an important visit amid the Russian invasion of Ukraine. Biden also took a PCR test, which came back negative ahead of his trip to Brussels and Warsaw on Wednesday.

It is the press secretary’s second time contracting the virus, which caused her to miss the president’s trip to the G-20 Summit in Rome last fall. This is Clinton’s first time contracting the virus.

Both are fully vaccinated and announced they would be quarantining. Psaki said she experienced “mild symptoms” and would conclude her quarantine after five days of isolation and a negative COVID-19 test.

Clinton said that both she and her husband, former President Bill Clinton, who tested negative, would be quarantined in their home until the “household is fully clear.” Hillary Clinton also described experiencing mild symptoms.

Last week, it was also announced that former President Barack Obama tested positive for the virus. The news of positive tests among multiple prominent political figures in the U.S. comes as Dr. Anthony Fauci warns of another wave of the virus.

With the dropping of mask and vaccine mandates and the removal of travel restrictions around the world, the number of cases has risen globally.
