Mexican President Andrés Manuel López Obrador announced Sunday evening that he's tested positive for COVID-19.
Driving the news: López Obrador tweeted that he has mild symptoms and is receiving medical treatment. "As always, I am optimistic," he added. "We will all move forward."
Worth noting: López Obrador has downplayed wearing masks, telling reporters last July: "You know when I'm going to put on a mask? When there is no corruption. Then I'll put on a mask and I’ll stop talking."
- He has also labeled lockdowns and face-mask mandates tactics of "dictatorship."
