The message, accompanied by a picture of the First Lady wearing a protective mask, contradicted US President Donald Trump’s comments regarding the masks. Mrs Trump said: “As the CDC continues to study the spread of the Covid-19, they’re recommending people wear cloth face coverings in public settings where social distancing measures can be difficult to maintain.”
“Remember,” she added, “this does not replace the importance of social distancing.”
The number of coronavirus cases and deaths in the US has exploded over the past couple of weeks.
Mr Trump had a very different approach to the social distancing guidelines.
During televised news briefings the US President told media outlets he would not wear a mask unless he thought it was necessary.
According to White House officials anyone who comes into contact with Mr Trump must undergo testing for the virus, including reporters in the White House briefing room.
On Friday Mr Trump told reporters: “I don’t know, somehow sitting in the Oval Office behind that beautiful Resolute Desk.
“I think wearing a face mask as I greet presidents, prime ministers, dictators, kings, queens, I don’t know. Somehow, I don’t see it for myself. I just — I just don’t.
“Maybe I’ll change my mind, but this will pass, and hopefully it’ll pass very quickly.”

The First Lady’s anti-bullying program focuses on promoting healthy online interactions among children.
On the other side of the coin, the US President has dedicated part of his online presence to undermining Democrats and political opponents.
In December, when Mr Tump appeared to 16-year-old climate activist Greta Thunberg, the First lady remained silent.
According to Stephanie Grisham, the White House press secretary at the time, the couple “often communicate differently.”
