Sen. Cory Booker, D-N.J., announced on Sunday night he has tested positive with a breakthrough case of the coronavirus.
Sen. Booker confirmed that he had received two doses of the coronavirus vaccine and the booster shot. He said that he first began feeling symptoms on Saturday.
"I learned today that I tested positive for COVID-19 after first feeling symptoms on Saturday. My symptoms are relatively mild," he said.
Sen. Booker described his symptoms as "relatively mild" and urged people to get vaccinated.
"I’m beyond grateful to have received two doses of vaccine and, more recently, a booster – I’m certain that without them I would be doing much worse," he said.
Sen. Booker is the second Democrat to announce a positive coronavirus test on Sunday, as Sen. Elizabeth Warren, D-Mass., announced she tested positive on Sunday as well.
"I regularly test for COVID & while I tested negative earlier this week, today I tested positive with a breakthrough case," Sen. Warren announced Sunday. "Thankfully, I am only experiencing mild symptoms & am grateful for the protection provided against serious illness that comes from being vaccinated & boosted."
"As cases increase across the country, I urge everyone who has not already done so to get the vaccine and the booster as soon as possible - together, we can save lives," she added.
The comments come as there is an increase in coronavirus cases nationwide, as Dr. Rochelle Walensky, the director of the Centers for Disease Control and Prevention, said on Friday that the current seven-day average of coronavirus cases is at near 119,500 per day.
Hospital admissions have increased about 4% compared to the previous week, and daily deaths have increased by over 8%.
Dr. Walensky insisted preventative measures must be taken as the omicron variant spreads throughout the country.
"We have vaccines, we have boosters, and we know multi-layer prevention strategies — masks in public indoor settings, practicing physical distancing, frequent handwashing, improving ventilation, and testing to slow transmission — are vitally important, especially as we prepare for more Omicron and even if you are vaccinated and boosted," Dr. Walensky said.
According to the CDC, there were 156,754 new cases of the coronavirus nationwide on Friday.
