Melania Trump's Twitter account favourited a tweet that showed the viral image of her quickly dropping a smile at her husband's inauguration as soon as the new President turned away.
The verified @MELANIATRUMP account briefly liked a tweet featuring the now-infamous image which read: "Seems the only #Wall @realDonaldTrump's built is the one between him and @FLOTUS #Melania #trump".
It was only the second tweet the First Lady's currently-inactive personal account had liked, though it removed it less than an hour afterwards on Tuesday.
Its last tweet was on 8 November last year, the day of the US presidential election, and featured an image of a "Vote #TrumpPence16" badge. Its other "liked" tweet was its own first message, a simple "Hello Twitter!" in 2012.
Ms Trump has a separate professional account—@FLOTUS—run by her office that promotes her activities as First Lady.
While President Trump has his own official @POTUS Twitter account, as favoured by his predecessor Barack Obama, he prefers to use his personal @Reuse content
