The 79-year-old has tested positive for the virus after being fully vaccinated and twice boosted

President Joe Biden said Thursday that he has tested positive for Covid-19 but will continue to work while in isolation at the White House despite his mild symptoms. In a video posted to Twitter, Biden told Americans that he is “doing well” and that his symptoms continue to be mild.

“I guess you heard, this morning I tested positive for Covid. But I’ve been double vaccinated, double boosted. Symptoms are mild and I really appreciate your inquires and concerns. But I’m doing well, getting a lot of work done. Going to continue to get it done and in the meantime, thanks for your concern and keep the faith. It’s gonna be OK,” Biden, said while unmasked and standing outside on the Truman Balcony. The White House says the 20-second video was filmed by a masked and socially distanced videographer.

Meanwhile, White House press secretary Karine Jean-Pierre was asked several times during the daily briefing where the President may have contracted the virus—especially since he recently returned from a trip to the Middle East with stops in Israel and Saudi Arabia. However, she said that it doesn’t matter where President Biden contracted COVID-19, and that the most important thing is that he was fully vaccinated and double boosted.

Then, reporters asked Dr. Ashish Jha, White House Coronavirus Response Coordinator, where Biden may have caught the virus. After Jha said he didn’t know, Jean-Pierre interjected to say again it’s not important.

At 79-years-old, Biden is at high risk for experiencing severe illness however officials say at the moment there is no talk of transferring power to the vice-president.
