(WASHINGTON, D.C.) — Former Vice President Joe Biden and his wife, Jill Biden, have both tested negative for COVID-19, according to Biden.

“I’m happy to report that Jill and I have tested negative for COVID,” Biden tweeted early Friday afternoon.  “Thank you to everyone for your messages of concern. I hope this serves as a reminder: wear a mask, keep social distance, and wash your hands.”

Not long prior to Biden’s announcement, the Biden-Harris campaign also released a statement announcing the same news.  An aide to Senator Kamala Harris, Biden’s vice presidential running mate, told ABC News that Harris and her husband, Doug Emhoff, had both tested negative for COVID-19 Friday morning.

The news comes after the White House revealed early Friday morning that President Trump and first lady Melania Trump had both tested positive for COVID-19, an announcement that came just hours after it was revealed Trump aide Hope Hicks had tested positive for the coronavirus and was displaying symptoms.

Though the White House initially said the president and first lady weren’t symptomatic, late Friday morning both were said to be displaying symptoms of the virus.

News of President Trump’s illness has set off a flurry of contact tracing among those who have been in recent close proximity to the president.  Other politicians have also revealed positive tests Friday morning, among them Republican Utah Senator Mike Lee and Republican National Committee Chair Rona McDaniel.
