The First Lady accepted the flower and then the US President gave her a gentle tap on the back before the couple departed for Georgia. The spontaneous show of affection sent social media fans into a frenzy with many commenting on “how sweet” the gesture was.
One Twitter user said: “What a sweet gesture. I love this couple.”
Another person posted: “The President demonstrating that he is an example of a man, loving, affectionate, respectful, humble, sensitive, simple, a great human being.”
A third social media user wrote: “Omg they are so cute.”
Some Twitter users compared Mr Biden to his predecessor Donald Trump.
“No it’s not earth shattering news, but it’s the job of the print pooler to note all the details of the president’s movements.”
During Mr Biden’s speech in Duluth, Georgia, he marked his 100th day in office and delivered his $4 trillion infrastructure proposal to fix America’s crumbling highways and bridges.
At the end of the speech, the President lost his face mask and appeared to slightly panic.
He said: “Looking for my mask, I’m in trouble.”
Thankfully an aide came to the rescue and handed Mr Biden a mask.
