Atlanta Mayor Keisha Lance Bottoms announced that she had tested positive for Covid-19.
The 50-year-old Democrat is among the women named as a potential vice-presidential running mate for presumptive presidential nominee Joe Biden.
"Covid-19 has literally hit home. I have had NO symptoms and have tested positive," Bottoms tweeted.
She told MSNBC that she decided her family members should get tested again because her husband "literally has been sleeping since Thursday." She said the only other symptoms she and her husband have experienced are those similar to allergies they have.
"It leaves me for a loss for words because I think it really speaks to how contagious this virus is," Bottoms told MSNBC. "We've taken all of the precautions that you can possibly take. We wear masks, we're very thoughtful about washing our hands, I have no idea when and where we were exposed."
